MATLAB: Undo textm on a map

Question

Hello, I created an interactive map using inputm and textm where user specifies quadrants on a map to exclude/include in analysis. After they click, I use textm to place a X there so that user knows where they have already clicked. I want to give users the option of changing their minds. How do I remove the X placed on the map? I tried another textm in same lat/long with empty string but it doesn't write over original marking.

Is there a way to remove the text that textm placed on a map?

Thanks

Answer 1

grab the handle to the text object, then you can delete it

h = textm(etc)

To delete

delete(h);
