How can I pass a third argument to @setDataTipTxt? This seems to be what the poster was referring to: @richard: I have data which I have plotted and shown in the question. I have a callback function outputTxt = myCallback(obj, eventObj) to create customized datatips as described here, but I need to limit that behavior to only work for certain objects (specifically, plotted data points only, and not other lines showing mean, standard deviation, etc.). %old_fig = a bunch of subplots etc position = [X(end),dataExtract(end),1; X(end),dataExtract(end),-1]; For example, the current data-cursor object can be gotten via cursorMode.CurrentCursor instead of using CurrentDataCursor. Simply find a way to get the contours data accessible in your updateFcn (there are multiple ways to do this, all of them pretty standard/documented) and youre basically done. This causes subsequent mouse clicks into the new (magnified) figure to be ignored, so they fail to fire the callback. %Move the data tip to the right most data vertex point I was able to find the handle for that panel and set its font to Courier New. BackgroundColor: [1 1 0.933333333333333] BeingDeleted: 'off' item8 = uimenu(hcmenu,'Label','Cursor Mode','Callback',@update_FCN_call); Anyway, if an empty string is not allowed, you can always try a sting containing a single space character. This is just a basic idea for identifying the region of negative slope. clc set(cursorMode, 'UpdateFcn',{@setDataTipTxt,sourceFilename}); Id tried what you told me, but it seems there is a problem when appending sourceFilename to the output cell array of @setDataTipTxt. function CursorMode_Off_test With fiber, distance is not an issue. But besides that it worked perfectly. When I make a datatip it displays: datacursormode on; Moreover, do you know if the same handle.listener syntax still works in HG2 to listen to java events ? I suggest that you contact support@mathworks.com to report it, In R2014b, MATLAB has a new graphic handle system, so the image is visualized in a different way, which affect the behavior of setting SnapToDataVertex off. hLine = plot(xdata, ydata); Any thoughts on why the appearance would change between the two display styles? I have not figured out how to do this programmatically unless I am creating the datatips programmatically and then storing them in my own cells. set(dcm_obj, 'DisplayStyle', 'datatip', 'SnapToDataVertex', 'off', 'Enable', 'on'); I can only select pixel (e.g. UpdateFcn: @setDataTipTxt Connectez-vous votre compte MathWorks; Mon compte; Thats it. position = [xdata(end),ydata(end),1; xdata(end),ydata(end),-1]; From the desktop click on the windows button in the bottom left I would like to remove the plot labels from Y axis and instead just place a P, IC, RA and O where the left labels are. yData = get(hObj, 'YData'); You cannot place them programmatically (by executing code to position a data cursor). I dont know if it always said that or if thats updated language as of R2014a/b. I was thinking I could get it to identify mins/maxs but I would still need to identify if the region is sloped downward. Here are the outputs Ive got at the prompt: >> dcm=datacursormode(figHandle) 9. Now that you can see the raw data it is time to add labels and a legend to your plot.

FWIW, Im stuck using a R2006b on this project. f=figure; cursorMode = Menu de navigation principal. end, followed by setting any figure callbacks you want to survive while datacursor mode is enabled, @Yair, I am almost certain that I have read it in one of your answers somewhere but I have forgotten about it. curves that are consistent with the discrete data above. We are proud to have worked with many manufacturers and vendors throughout the Southeast to provide the highest quality products and services available to our customers. interp1 will match the graph exactly, but you might be interested in fancier curve-fitting operations, like spline approximations etc. indAxes = find(figAxes == gco); The Deleting data tips section above shows how to do this from the parent script, but Im wondering if it is possible to do this _from within the callback_. To modify the appearance of a data-tip, we first need to get access to the hDatatip object that we created earlier, either programmatically, or interactively (or both). Other MathWorks country j = get(h, 'TextBoxHandle'); matlab, how to get the data point from the plot. How to plot like this? Understanding it by simply reading the code (under %matlabroot%\toolbox\matlab\graphics\) is actually pretty difficult. @Mike you can modify the tip background via the TipHandle and/or BackgroundAlpha: hDataTip.TipHandle.FaceColor = 'm'; % or: [1,0,1] I try to zoom in the graph and get the exact value of the plot at some specific hcb3 = ['set(gco,''LineStyle'',''-'')']; Draggable: 'on' An easy way to do this is to click the figure to bring it to the foreground. Figure: [1x1 Figure], So not nearly as many properties are listed as above. For example if the data is. Then a panel is created to hold the same content that is in the data tip. The first two errors are not a big deal, but I dont know what to do about update no longer working.

Figure: [1x1 figure] This method has however few drawbacks: X: 3.669e+05 I was hoping you could help me with a minor predicament. @Nick all you need to do is to set a custom UpdateFcn callback function for the cursorMode object (in my post it was @setDataTipTxt). set(get(hDatatip, 'DataCursor'), 'DataIndex', index, 'TargetPoint', pos); Seems much more likely that its my fault and not Matlabs, but any chance this could be an HG-related bug? How did muzzle-loaded rifled artillery solve the problems of the hand-held rifle? 'matlab.graphics.shape.internal.DataCursorManager'. I am writing a program with 4-context menus; one of them is related to datacursor mode, I can switch between any of them except datacursormode one, I CANNOT Switch it off, So pleae how to do it in some example demo? Learn more about plot, simulation MATLAB. For irregular curves, you might try spline fitting. txt = sprintf(''); @Graham data-tips are simply axes text objects, so they can be formatted with Tex/Latex but not HTML. Learn more about plot, simulation MATLAB. Examples of frauds discovered because someone tried to mimic a random sequence. Im new to matlab so this is likely to be a very basic question but I havent been able to find an answer so far. How can I do that, please? I have explained in the past how to programmatically control data-tips, but doing so relies on the figure datacursormode, which is figure-wide []. call it old_fig. Try adding a drawnow; pause(0.1); after the figure creation and before you retrieve datacursormode, maybe it will help. Hello, hObj = plot(x,y); You can find the maximum point using the m a x and f i n d commands in Matlab: y m a x = m a x ( y); x m a x = x ( f i n d ( y == y m a x)); The other points do not exist in your data, i.e. Site design / logo 2022 Stack Exchange Inc; user contributions licensed under CC BY-SA. Could you give an example of what the equivalent syntax looks like in HG2 ? set(hDatatip, 'Host',hTarget); Why does my stock Samsung Galaxy phone/tablet lack some features compared to other Samsung Galaxy models? Products | Hi. Hi Yair, Im running R2011b & interested in being able to provide links with matlab: href to trigger some activity. clf y = sin(x); MATLAB has various functions that can be used to display data graphically. Hi Isaac! There are actually two ways to do this: Host: [1x1 graph2d.lineseries] title ('Right Side') sgtitle ('Sitting MEP for 5 sec') There are a couple of things i would like to clean up from this graph. set(cursorMode, 'enable','on', 'UpdateFcn',callbackhand, 'NewDataCursorOnClick',false); ['SubName', mat(pos2).name]}; By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. HitTestArea: 'off' I need to write the x axis difference between two or 4 datatips on the plot like legend. Ive received an answer from the MATLAB support and they have sent a workaround for MATLAB R2014b to get the exact cursor location on an image. If you find anything useful, come back here and post it for the benefit of other readers. You see the blank space for the plot. I found interactive fitting tool in Matlab simple and helpful, though somewhat limited in scope: The graph above seems to be linear interpolation. The basic way is to search the relevant axes for objects that have Tag=DataTipMarker.
