Yair Altman (8 days 0 hours ago): Dom – call drawnow *just before* you set hLine.MarkerHandle.FaceColorTy pe to 'truecoloralpha'. Also, you made a typo in your code: it’s truecoloralpha, not...
Dom (8 days 22 hours ago): Yair I have tried your code with trucoloralpha and the markers do not appear transparent in R2021b, same as for Oliver.
Yair Altman (12 days 6 hours ago): Ren – This is usually the expected behavior, which avoids unnecessary duplications of the Excel process in CPU/memory. If you want to kill the process you can always run...
Yair Altman (12 days 20 hours 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...

Sagar Chawla (65 days 23 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 (66 days 0 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...
