Yair Altman (10 days 11 hours ago): @Veronica – you are using the new version of uitree, which uses HTML-based uifigures, and my post was about the Java-based uitree which uses legacy Matlab figures. For...
Veronica Taurino (10 days 11 hours ago): >> [txt1,txt2] ans = ‘abrakadabra’
Veronica Taurino (10 days 11 hours ago): Hello, I am just trying to change the uitree node name as you suggested: txt1 = 'abra'; txt2 = 'kadabra'; node.setName([txt1,txt2]); >> "Unrecognized method, property, or...
Yair Altman (13 days 11 hours ago): The version of JGraph that you downloaded uses a newer version of Java (11) than the one that Matlab supports (8). You need to either (1) find an earlier version of JGraph that...
mrv (13 days 16 hours ago): hello, I used MATLAB 2019b update9, I have add jgraphx.jar to javaclassapth, and restart matlab, but still got errors below: Warning: A Java exception occurred trying to load the...
xuejie wu (37 days 11 hours ago): Hi: I’m wondering if i can add my customized section or tab ?
Yair Altman (49 days 3 hours ago): @Sagar – use the view(az,el) function to rotate the 3D axes.
Sagar Chawla (49 days 3 hours ago): I want to know how to change the x-axis to the z-axis. I mean the position. Like if there is a 3d animated graph then how to change position of the axis. X-axis in place of...
Ren (49 days 4 hours ago): I noticed that xlsread will create a hidden and never-dying special server that always has priority when actxGetRunningServer is called. So this cause a problem that no matter how many...
Ben Abbott (52 days 19 hours ago): Thanks Yair, it was the second. I didn’t not include the drawnow ()
Yair Altman (52 days 22 hours ago): @Ben – it looks perfectly ok (with color gradient and all) on my R2022a… Perhaps you missed some of the steps (e.g. setting the ColorBinding to 'interpolated') or...
Ben Abbott (52 days 22 hours ago): The graded color is not working for me using R2021a. The plot “HG2 plot line color, transparency gradient” looks exactly like “Transparent HG2 plot...
Yair Altman (76 days 1 hour ago): Oliver – you probably forgot to update hMarkers.FaceColorType to ‘truecoloralpha‘: x=1:10; y=10*x; figure; hLine = plot(x,y,'o-'); drawnow...
Oliver (76 days 1 hour ago): This seems to have been disabled in the most recent version of Matlab (R2021b). When I use this method the hMarker.FaceColorData does change, but the markers are not made...
Yair Altman (94 days 23 hours ago): @Tim – the new uidatepicker() function only works with web-based figures (created using the uifigure() function or App Designer); it is not available on the legacy...
