Yair Altman (7 hours 35 minutes ago): When you use plot() without hold(‘on’), each new plot() clears the axes and draws a new line, so your second plot() of p2 caused the first plot() line (p1) to be...
Cesim Dumlu (6 days 15 hours ago): Hello. I am trying to do a gradient plot for multiple functions to be displayed on the same axes and each one is colorcoded by respective colordata, using the same scaling. The...
Yair Altman (14 days 18 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 (14 days 18 hours ago): >> [txt1,txt2] ans = ‘abrakadabra’
Veronica Taurino (14 days 18 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...

Ren (53 days 11 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 (57 days 2 hours ago): Thanks Yair, it was the second. I didn’t not include the drawnow ()
Yair Altman (57 days 5 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 (57 days 5 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 (80 days 8 hours ago): Oliver – you probably forgot to update hMarkers.FaceColorType to ‘truecoloralpha‘: x=1:10; y=10*x; figure; hLine = plot(x,y,'o-'); drawnow...
