I would like to be able to save a plot to a file that I can later load back and edit in Octave.

This is what I tried. . .

close all
bar(1,1) % create figure with a rectangle drawn in it
hold on
hgsave(“temp”) % Saving to file temp.ofig.

close all
hgload(“temp”) % Load the figure back in. Figure comes up looking good.
bar(2,1) % This command is actually performed properly. But I get the following error msg
% which aborts the program.

error: get: invalid handle (= -4.14413)
error: called from
_bar_>update_xlim at line 352 column 7
_bar_>bars at line 335 column 3
_bar_ at line 194 column 12
bar at line 118 column 16

If I remove the “hold on” line, I don’t get the error message. But, of course, the rectangle that I previously saved will be gone.

Am I missing something here, or is this not working properly? Maybe I should be doing this a different way?
