Matlab normalized figure coordinates Learn more about figure, size . Finally, look closer at the example I provided - X and Y are 1x2 arrays that provide coordinates (i. % Define helper funcitons to normalize from axis coordinates to normalized position in figure. e. Hello, I have a problem with determining the end of the axis in normalized coordinates. You can get the 'Position' property for all the controls on the figure window, and then dynamically place things. 3]) requires The ‘Position’ property sets the size of the figure (in pixels by default). Stack Overflow for Teams Where developers & technologists share private knowledge with coworkers; Advertising & Talent Reach devs & technologists worldwide about your product, service or employer brand; OverflowAI GenAI features for Teams; OverflowAPI Train & fine-tune LLMs; Labs The future of collective knowledge sharing; About the company Finally, look closer at the example I provided - X and Y are 1x2 arrays that provide coordinates (i. With a few lines of code, you This utility function converts coordinates in data space into normalized figure coordinates, for input to annotation. All the points in between can be represented as pairs It would be helpful if MATLAB provided annotation available for data coordinates. Hello, I am trying to position my annotation arrows onto a 2D XY plot but it seems that annotation x and y points can only be in normalized units. First, by default, the alignment of the text in an annotation text box is in the upper right corner. 'normalized' These units are normalized with respect to the parent container. MATLAB Concepts. The ‘Position’ property sets the size of the figure (in pixels by default). Hiya other units can be set like 'pixel' to specifically set the number of pixels but i usually stay in normalized such that they get scaled depending on which computer or monitor setup i have. However, to ensure that I will get the same snapshot on another computer, how can I give rect in normalized coordinates? Learn more about signal processing, plot, data, data acquisition, extract, figure Dear All, I am looking for your kind help to my question. However, to ensure that I will get the same snapshot on another computer, how can I give rect in normalized coordinates? The trouble is, I want to use the coordinates from the plot, not the "normalized" figure coordinates. axes([0. Hughes. Because the ginput points are in respect to the axes of the plot and the normalized points (used with the "annotation" command) are in respect to the whole figure, I can't figure You need to access the 'Position' property of the figure object you’re using. I want to click in a Matlab figure and find out the x and y position of the clicked position. So, this is how you get from figure window axes to plot axes and vice-versa. Origin of the local coordinate system, The MATLAB ® and Communications Toolbox™ products do not use this definition. The following example, extracted from the documentation, adds a text arrow to the graph by defining the text arrow to start from (0. Hopefully the documentation will make it clear which 4 tuple is expected in the respective case. It Annotations are a pain to use unless the axes are normalized to 0:1. e. I have an image that I would like to get the coordinates from. which needs normalized figure units. This figure illustrates the azimuth and elevation angles of a direction vector. The lower left corner of the figure 2 shows the actual (normalized) please note that only y axis has been normalized and logarithmic sca Skip to content. Lesson: I. However, say that I have plotted a graph with plot(t, sin(2*pi*t)). The 3rd one is covered up by the data tip. The matlab application I am using is located here. Change Figure Size. Normalizing RGB coordinates in an image. set(gcf, 'Units', 'Normalized', Find the treasures in MATLAB Central and discover how the community can help you! Start Hunting! Beginning and ending x-coordinates, specified as a two-element vector of the form [x_begin x_end]. Is this possible? Using the accumarray function, it is possible to get other parameters of the concentration, such as the mean or median values, as well as standard deviations (std and metrics derived from it, such as confidence intervals) and plot them also using the patch function (although that is more complicated and requires calculating them in polar coordinates and then The ‘Position’ property sets the size of the figure (in pixels by default). However, to ensure that I will get the same snapshot on another computer, how can I give rect in normalized coordinates? Centering values, returned as an array or table. the result of this has to be normalized from 0 to 1. This means that you have to normalize your coordinates to the figure. This function can be used for adding annotations in the figure, for hi, i need to plot a arrow in my image. Doing this fix for position works for me, if there is only one set of axes in the figure but not for multiple axes. t axes to get position w. 47 6 6 bronze badges. I am drawing multiple regions of interest on an image and I need to document the position of each to inform anoother script. Skip to content. I have gone through a whole bunch of posts in Matlab and stack overflow but nothing is working. It Because the ginput points are in respect to the axes of the plot and the normalized points (used with the "annotation" command) are in respect to the whole figure, I can't figure out how to convert from plot coordinates to normalized so that I can use the annotation function. Below is an example, putting all these ideas together. I grew to like IDL and now I mostly program in python and am starting to get into Julia. 0, 26 June The problem is, even if I use 'Normalized' units and put '[0 0 1 1]' for 'OuterPosition', it does not fill the Beginning and ending x-coordinates, specified as a two-element vector of the form [x_begin x_end]. The Position and Units graphic object properties Many graphic objects (e. The recording of these coordinates will Beginning and ending x-coordinates, specified as a two-element vector of the form [x_begin x_end]. When I try to make a MATLAB figure fit the screen it only gets a size big enough to fit the laptop (screen_number) %screensize: return screen coordinates of multiple monitors. The I want to use the getframe() option to make a snapchat of a part of my figure. axishandle must be a valid MATLAB axes object (HG2) or handle (HG1). While using annotation function, you may want to transform data space coordinates to normalized figure coordinates. Find the treasures in MATLAB Central and discover how the community can help you! Start Hunting! (Since plotting text in normalized coordinates is not affected (hidden) by the surface). r. The lower left corner of the axes maps to (0,0) and the upper right corner maps to (1,1). Apparently, the axes referred to here are not the "mathematical" (3D) axes of the graph, but the "canvas" How can i convert the axis coordinates into pixel coordinates? %# and also have points outside the image boundary figure, imshow(I) hold on, plot(x,y, 'LineWidth',2) axis we need to add 1 since MATLAB indexes from 1. hphys hphys. . The lower left corner of the If no figure exists with that property value, MATLAB ® creates a new figure and sets its Number property to n. You can do two things. Sign in to answer this question. However, the documentation says that getframe(__, rect), the rectangle coordinates are in pixels. You can easily locate annotations anywhere in the figure. The intention is to make a binary image from the green one. Each value in C is the centering value used to perform the normalization along the specified dimension. But they can't work at 3D axes. I have a Matlab function that requires the vector to be in pixels. Can any returns the color values of the pixel at row 2, column 15 of the multi-channel image RGB. The lower left corner of the In MATLAB, the coordinate of the figure window is normalized (because I used 'Units', 'normalized' in my code). Convert from dataspace to figure units to make it easier to add annotations pointing to data in a MATLAB figure window. figure() also permits you to pass in name/value pairs. The annotation function, which allows you to programmatically add a wide range of annotations to your figure, requires coordinates to be specified in normalized figure units. Text location. It is common to switch the Units of an axes to Pixels; if that is done before changing the OuterPosition, then the OuterPosition would report back in that new units and adjustments would be relative to that The command axes creates an axes object (see: doc axes). Commented Oct 11, 2011 at 8:41. I've thought for 30 years that builtin functions to do the conversion from figure coordinates to the axis limits positions should be available and well documented how to use them with annotation; as is, all the examples there are black boxes with magic numbers for positions that make no sense just to look at as far as where the objects shown are with respect to the When you use Normalized units you need to define the position between 0 and 1, with 0 being the bottom/left hand side and 1 being the total height/width of the containing object. I've only needed the coordinates inside the image itself. In a spatial coordinate system, locations in an image are positions on a continuous plane. Help Find the treasures in MATLAB Central and discover how the community can help It would be helpful if MATLAB provided annotation available for data coordinates. It's in pixels. Having said this, I want to draw attention to our two main steps. Like dsxy2figxy or ds2nfu, also work for 3D axes. That should give you the desired outcome. Create a default figure. 5,0. To correctly convert the Consider the following code. You can see 2 on the figure below. , based on the values of data displayed in an axes). (I want to know if I am right here. In my code, I would like the arrow pointing to the point annotation requires us to specify the annotation’s position in normalized figure units. Learn more about text, figure, unknown, coordinates MATLAB Hi i have a csv file the problem is my data has random x,y values so it changes according to machine but i want to display a value on the figure. Sign in to comment. For example, if A is a 10-by-10 matrix of data and normalize operates along the first dimension, then C is a 1-by-10 vector containing the Beginning and ending x-coordinates, specified as a two-element vector of the form [x_begin x_end]. 3,0. [Xf, Yf] = DS2NFU(X, Y) converts X,Y are theta,r polar coordinates from % data space to normalized figure units, using the Similarly, the values Vx, Vy and Vz are the coordinates of a point on the V axis which has a unit distance from origin. annotation('line',x,y) creates a line annotation object that extends from the point defined by x(1),y(1) to the point defined by x(2),y(2), specified in normalized figure units. But it is not clear if painter rendering can Annotation objects are children of the figure. I am firmly entrenched in emacs and I detest the matlab editor. The annotation () function in MATLAB requires the X and Y coordinates for the object in normalized units. Normalize axis scale for annotations. You are currently defining the position using numbers that are well out of this range. So my question is: How to convert a 3D data point to a 2D normalized figure point? Download and share free MATLAB code, including functions, models, apps, support packages and toolboxes While using annotation function, you may want to transform data space coordinates to normalized figure coordinates. I have a figure comprising multiple plots with a number of additional text objects. When I plot a line for some data, I want to show the line's slope is a certain and work in normalized figure coordinates which can also be difficult. text(x,y,'Test','FontSize',20,'Units','normalized'); to plot the text on the 3D graph. How can I rescale them so that Download and share free MATLAB code, including functions, models, apps, support packages and toolboxes. This is useful for functions like annotation, where the input XY coordinates are normalized to the parent container of the plotting axes object and not to the data being plotted. i dont understand this window much so maybe my output is wrong for i=15:55 for j=2:9 plot (i,j) end end for the above program, I want to display the coordinate of the point near the point in the figure. Normalized with respect to the axes. % Learn more about #textbox #plot #figure MATLAB. I am not interested in getting the plot-dependent coordinates of a point selected by the user (I would use ginput for that like in this answer). 0. This would, in my opinion, actually be far more useful than the current annotation that works only with figure coordinates. It I just need to get the ROI in pixels (relative to image, not figure) using rbbox, but I'm having a hard time converting from normalized figure coordinates of the rbbox to image coordinates. ("View space"). If you are using 2D axes you can use dsxy2figxy or ds2nfu. And the default syntax: plt. Does anyone know how to convert matplotlib data units into normalized units? The reason that I need it is that I need to create a subplot on top of another plot. There are several functions where normalized figure coordinates are used. I clicked on 3 dots and 3 coordinates were returned to the command window. Learn more of an image, and made the following code. Then project into a plane, but transform also "z" coordinate, so still is 3D data. In this particular example the container is a figure(), but if you had happened to use uipanel() then the normalized coordinates would be relative to the containing panel. % Current mouse location, in pixels from the lower left. Understand the positioning of text in a text object. For Cartesian, we have a nice solution. I commented the code block, hopefully it's more clear. This works because, according to the documentation, 'normalized' units are. I am using the following How to draw an arrow using non normalized Learn more about units, arrow, plot Beginning and ending x-coordinates, specified as a two-element vector of the form [x_begin x_end]. So I am not converting it myself. Learn more about axes, plotting, graphics MATLAB Normalize XY coordinates to MATLAB figure window containing axis % XY coordinates are normalized to the parent container of the plotting % axes object and not to the data being plotted. Example: p = parallelplot(__,'CoordinateTickLabels',{'Height','Age','Smoker'}) You can use the imref2d object to facilitate conversion between intrinsic coordinates, world coordinates, and array indices. (0,0) coordinate is the bottom-left corner, and (1,1) is top-right coordinate. example. This is especially useful if you plot the image using custom XData/YData locations other than the default 1:width and It would be helpful if MATLAB provided annotation available for data coordinates. Assume the normalized position is (x,y), then I could use. The problem is that when I look at the 4 new entries of the Position I see a "mix" of units, where the X,Y coordinates are in centimeters, but the width and height entries are the ones that it had first when the Legend Units were in 'normalized'. D. The UIFigure has a default position of [1 1 1920 1080] and fits to my screen very nicely and maximizes very well. I used those 3 coordinates to add 3 red X's. At the moment I am using the drawrectangle function but it is giving me the position of the ROI in pixels. Often, we are interested in an annotation on a plot axes that does NOT span the entire figure’s content area. However, it only permits that if you did not pass in a handle. Instead, I would like to return the coordinates in the [0,1] units of a given point on a plot (e. That positioning is done before the box is trimmed to the text, which leaves the text floating pretty far from the desired location. (*) The position in this example in given in normalized figure coordinates. I know, the coordinates of the endpoints and the distance from one of the point. Each coordinate tick label appears directly below the ruler displaying the values for that coordinate variable. Matlab has the ginput for getting the (x,y) value of where you have clicked on the graph. File Exchange. collapse all. One way to do this is with annotations, but there are some drawbacks (see below). end Share. I want to be able to have the cursor move on the actual plot, and by clicking it, I get the (x,y) coordinate of my plot (in this case, the time and the value of sine). asked Oct 27, 2017 at 13:52. And this utility function do this. I need say 1000 points from its boundary. I guess boldly, you have confused the extent of the figure with the extent of the axes, which contains the observed object. is it same as rectangular window. The text needs a pair of coordinates to locate it in the figure. Follow edited Oct 29, 2017 at 1:56. Some annotations require you to specify (x,y) pairs, while Is it possible to convert the last position (0,-0. However, it's only working for my display; on anyone elses it does not scale correctly. This means that you have to normalize your coordinates to the figure. Figure menu bar display, specified as 'figure' or 'none'. The MenuBar property enables you to display or hide the default menus at the top of a figure window. A. Use text() (or annotation) to write the labels. – reve_etrange. , A. 2, 'Lorem ipsum dolor sit amet, consectetur adipiscing elit,' ) then assuming that the numWords variable containing the total number of words in the sentence is available, how can we find the (x,y) coordinates of the i-th word? This is the normalized b-scan data. van Dam, S. I found the begining of the axes with the function: ax y point on the plot in normalized coordinates as I need to automate the annotation insertion on automatically generated graphs. Then more matrix to change CS to the one "seen" by a camera. % Version: 1. One very annoying thing about them is that they work in so-called normalized coordinates, which span the whole figure window (not just the plot area) and go from [0,0] to [1,1], forcing you to convert to these As the question states, I would like to obtain the screen coordinates of a given point on a plot. When I execute the following command: figure(' ;units One possible workaround is to get the coordinates of the screen where you want the figure window to It would be helpful if MATLAB provided annotation available for data coordinates. % Enlarge figure to full screen. This is more efficient than speculating, that something more complex happens for normalized units. (x,y) pairs) of where the arrow should start and where it should end. hphys. in this log average i have to use a rectangular region. hFig = ancestor(hAx,'figure'); try: print('-painters','-dpng','myFile') or. With best Below is an example, putting all these ideas together. It shows how to convert from axes coordinates to image pixel coordinates. for the first point I want to display (15, 2) Like dsxy2figxy or ds2nfu, also work for 3D axes. But I promise: The normalized coordinates are very simple. in this LL i have to do a log average transform.

First you should convert your data point from data-space to figure space which will reqiure 1) knowing the data point's (x,y) coordinates, 2) knowing the x and y axis limits, 3) knowing the position of the Learn more about getframe, figure, snapshot, image, image analysis, image processing I want to use the getframe() option to make a snapchat of a part of my figure. for the first point I want to display (15, 2) It would be helpful if MATLAB provided annotation available for data coordinates. Once we are dealing in the same units, we transform the position of the label w. Specify 'figure' to display the menu bar. Search Answers Answers. This last "box" CS is called "Normalized Device Coordinates system" (NDC). I agree it is a pain and they should have a version of annotation that works just on the main part of an axes within the bounding box (i. In all the years I've used MATLAB I've never had to mouse around outside an axes and get the (x,y) coordinates. axishandle must be a valid % MATLAB axes object (HG2) or handle (HG1). It would be helpful if MATLAB provided annotation available for data coordinates. Answers (0) Sign in to answer this question Collection of miscellaneous shared utils for Matlab - djoshea/matlab-utils Beginning and ending x-coordinates, specified as a two-element vector of the form [x_begin x_end]. annotation requires us to specify the annotation’s position in normalized figure units. This property affects only default menus, and does not affect menus defined with the uimenu command. The "normalized" property is not yet supported in app designer so I have to use the pixel units. Switch the units to normalized in seperate function call (demonstrated below) Note also that the units of these coordinates are specified in normalized figure units. I have this image and need to find the coordinates of a pixel nonzero of the points marked in red in image. When A is an array, normalize returns C and S as arrays such that N = (A - C) . Open Live Script. A solution is to use 'normalized' units for the text object. Again, a callback is triggered whenever the user moves their mouse in the figure, and the mouse coordinates are displayed in the textbox. 3D data space coordinates to normalized figure coordinates conversion Version 1. The below code should have worked but it didn't. Annotations enable you to place various graphic objects into your figure. The problem requires matching solutions at , using continuity condition for the function and demanding the integration equals to 1 of the eigenfunctions (normalization condition). Search File The outut coordinates are the normalized coordinates of the figure window, instead of the x- and y-coordinate. I am implementing in MATLAB. F. The axes is using normalized coordinates, which are relative to the figure. With regard to the reverse normalisation, I am not sure how the default MATLAB normalisation works. I already tried to multiply it by: image size, figure size, screen size, (image size) / (figure size). It is created with 'normalized' units, such that the position [0,0,1,1] fills the complete window: Start at point 0,0 in the left bottom and use the full width and height. Hi The inverse calculation converts coordinates from normalized coordinates to axes units; X_scale, Y_scale are the plot axes coordinates for point X, Y in normalixed units. One set of text objects needs to be positioned in the vertical, one text line per row of plots (plots are n by m The ‘Position’ property sets the size of the figure (in pixels by default). Axes position is normalized from 0 to 1 in the figure window, whereas the patch coordinates depend on the axes limits. Improve this answer. So if your x-values are in the interval of [0,59], then to get the coordinate that is "normalized to the figure" you would have to divide it by 59 so that the new interval is [0,1]. I am looking for a way to find x-axis points for a particular y-point, for example in the attached figure i need to find x-axis points It would be helpful if MATLAB provided annotation available for data coordinates. MATLAB-Dataspace-to-Figure-Units. It's not going to work on Windows or if wmctrl isn't installed. The recording of these coordinates will I have subplot on a figure and i want to place some text outside the plot as below There is a considerably shorter way to find the normalized desired y coordinate, Find the treasures in MATLAB Central and discover how the community can help you! Start Hunting! Why does the figure window with normalized units Learn more about multiple, monitors, matlab, normalized, units, screensize, scree, width, figure, position MATLAB. 10. It gives the left lower corner coordinates and the width and height values. 1,0. ). The annotation extends from the point (x_begin, y_begin) to (x_end, y_end). f = figure; Get the location, width, and height of the figure. Adjust it if you are using another figure coordinate system Yes, the patch coordinates are different from the axes position coordinates. I need to convert this vector of normalized units to units of pixels. I need to I have this basic structure of a thermal fin. Learn more about text, location . " "% Transform from data space coordinates to normalized figure coordinates. I see no reason why Matlab cannot allow users to specify the units in annotations which would make the tool a lot more useful. I know that there is an inbuilt function in matlab called "annotation" which does the job, but it needs to normalize the axis in the range of [0 1]. print('-painters','-dsvg','myFile') Logic: from documentation appears that the model of rendering is changed from painter (what you intended) to OpenGL when saving the file. Improve this question. I used ds2nfu for a while, and it gets close, but I use daspect([1 1 1]) and get(gca,'Position') doesn't properly get the normalized axes size when one axis is smaller due to the aspect ratio constraint. K. Is it possible to wait for the user to click a point then store the X coordinate (or index) of this point to a Learn more about plotting MATLAB. ) Wx, Wy, Wz is calculated as ((normalized u) X (normalised v)) (Also, if it This can be done of course by computing the figure’s dimensions and position in screen pixel coordinates, and the internal figure components dimensions/position within the figure, and their internal components and so on, not forgetting to translate data or normalized coordinates into screen pixel units, and taking care of logarithmic and reverse axes. % When the units of the figure are 'normalized', the % coordinates will be [0 0] inb lower left, and [1 1] in % the upper right. If you post your code, we can find the bug. Learn more about cordinates, axes, plot MATLAB. If you specify the labels as a categorical array, MATLAB uses the values in the array, not the categories. In MATLAB, I can select a data point using the Data Cursor tool and it will display the X and Y of that point (see figure below). onto the matlab figure, using normalized text options from [0,1], text(0. But all my color-normalized Skip to content. 6) and extend to (0. I'm trying to draw an arrow in matlab graph, without any success. MATLAB Answers. Understand the coordinate system of axes objects. COORD2NORM returns discrete arrays xnorm and ynorm of the same size as the input XY coordinate arrays. Since the axes position is being fixed, it shouldn't change WRT the figure, regardless of the presence or My problem is translating data coordinates into figure coordinates for dragrect. Because the ginput points are in respect to the axes of the plot and the normalized points (used with the "annotation" command) are in respect to the whole figure, I can't figure out how to convert from plot coordinates to normalized so that I can use the annotation function. , figure and axes objects) have a Position and Units property . g. Also tried to use the axis position. You will need to do the conversion to align the patch and axes. The primary issue is that it's not platform-agnostic. Together the x and y input arguments determine the endpoints of the line, arrow, double arrow, or text arrow annotation. Feiner, and J. 5) in normalized figure coordinates: i guess no,the value is coming 0. I want to use the getframe() option to make a snapchat of a part of my figure. Specify 'none' to hide it. With some matrix math you change every vertex coordinates to a unique, common to all, CS, the "World space". It's inconsistent to have provided text(X,Y,str) using X and Y in data coordinates and not annotation using data coordintes. Note also that the units of these coordinates are specified in normalized figure units. In the last versions of Matlab you can use the function annotation() to create some annotation objects in the figure (such as arrows). not including tick labels, title, etc. t figure. for the first point I want to display (15, 2) Yes, the patch coordinates are different from the axes position coordinates. A few things are happening here. The lower left corner of the The annotation function, which allows you to programmatically add a wide range of annotations to your figure, requires coordinates to be specified in normalized figure units. for i=15:55 for j=2:9 plot (i,j) end end for the above program, I want to display the coordinate of the point near the point in the figure. 5) to a 2D normalized position? (Since plotting text in normalized coordinates is not affected (hidden) by the surface). If the coordinates were inaccurate, they would not have matched the 3 points I clicked on. The problem is that axis positions are in figure space (relative to lower left corner of the figure) while the data point coordinates are in data space (relative to the origin). Code this way you don't have to deal with unhandy normalized figure units by use of annotation. The individual plots are positioned in normalized coordinates and most of the additional text is positioned in a page-size axis system using inches. The lower left corner of the Yes, the patch coordinates are different from the axes position coordinates. References [1] Foley, J. Help Center; Find the treasures in MATLAB Central and discover how the community can help you! Start Hunting! I am literally drawing a line onto the figure manually (via insert --> line), and MATLAB reports the position of that line in normalised figure units. However, my MATLAB implementation does not yield solutions that match well (there is a certain jump there) at . 0 (4. Spatial Coordinates. Locations are described in terms of Like dsxy2figxy or ds2nfu, also work for 3D axes. In general possibilities are (left, bottom, width, height) (this is called "bounds" in matplotlib); or (left, bottom, right, top) (called "extent"). I would like to place my annotation arrows usin The ‘Position’ property sets the size of the figure (in pixels by default). That probably means that the majority of users can't use this simplified code out of the box, and I don't feel like relying on everyone to read the FEX description before they download it and get disappointed. I don't fully understand what you are asking for. First, we match the units for the position of the label with the units for the annotation function. I am trying to find the coordinates of a point on a straight line. the thing is i have to do dwt then get the low frequency (LL)component. You will have to work the position(*) by yourself though, and this position is relative to the figure (not the axes), but it is saved with the figure so it will be where you left it every time you load the figure. Its a 2D image. Is there any way in matlab, I can import the image, and save the (gcf, 'Units', 'Normalized', 'Outerposition', [0, 0, 1, 1]); % Extract the Beginning and ending x-coordinates, specified as a two-element vector of the form [x_begin x_end]. To correctly convert the This function returns normalized coordinates in plot, semilogx, semilogy and loglog plots. Specify the property as a vector of the form [x y width height], where x and y define the distance from the lower-left corner of the screen to the lower-left corner of the figure. 2. By default, the units are normalized to the figure. I have found that I almost always want to specify my annotations in data space (i. An utility function to help annotation. In the case of the legend there is an option to place it in different positions through the property "location". The If all that fails, I'd call the Mathworks. However, Units is currently set in 'centimeters', so the legend is "trying" to be super small. /S. Convert Axes Coordinate into Intrinsic Coordinate. Understand how to set default values for graphic object properties. Thanks – In the example, the figure isn't using normalized coordinates. This should be an easy one. I realize that you can ask matlab to use emacs as the editor but then I have been unable to set up breakpoints which can be very handy, so I typically just use the horrible matlab editor. Follow While using annotation function, you may want to transform data space coordinates to normalized figure coordinates. I use "file", "generate code" to get the position of a text box in Matlab normalized units per my example. However, to accurately place objects, (without using GUI) we would " How do I convert these pixels to normalized cooridinates? You can do the conversion yourself by dividing the ROI pixel dimensions by the pixel dimensions of the image. Assume the normalized position is (x,y), then I could COORD2NORM(axishandle, x, y) takes input XY coordinates, relative to the axes object axishandle, and normalizes them to the parent container of axishandle. Define the location of annotation objects in normalized figure coordinates: lower left = (0,0), upper right = (1,1), making their placement independent of range of data represented by the axes. 06 KB) by MinLong Kwong Like dsxy2figxy or ds2nfu, also work for 3D axes. 7,. Examples. I suspect that OpenGL does not respect you intentions and forcing the renderer to painter will solve the problem. icvd zlwa yqfhrb fjoc afxs ewefngr emc mwfj aomtxq ubwku
