Hello,

The following code segment works fine in the MATLAB command window. It produces the expected figure and saves it. The saved figure, TdfOverlayPspec.fig, can be opened (open('TdfOverlayPspec.fig')) and is the same figure that was saved.

When this same code segment is run in LIVE EDITOR, it produces the TdfOverlayPspec.fig file, but the file does not open. There is no error reported and the 'open' command appears to be executed but no figure is displayed. I have checked to see if it was produced off monitor and this is not the case.

The file, TdfOverlayPspec.fig, produced is the same size whether generated from the MATLAB command window or for LIVE EDITOR.

Looking forward to any help you can provide.

Thanks,

RC

check to see if the loaded figure exists but has visible off

Thank you for your comment Walter.

Though the default for the visibililty property is 'on' for the figure command, this apparently is not true when running in the live editor. By changing the command to figure("Visible","on"), the saved figure became visible when opened.

Again, thank you for your help.
