How to add boarder to specific value of image plot?

Share icon

Hi all,

I have an image plot with values between 0 and 1 (see attached image). What I hope to do is to add emphasis such as boarder to grid with values greater than 0.5, an example drawn manually with other software is as attached (see the arrow). I hope to add boarder to all grid that satisfy the given condition in Igor. Is there a way/function to do that?

Thanks,
William
You can write code to call the DrawRect command. Before the DrawRect command, call SetDrawEnv to use the bottom and left axes for your x and y coordinates.
