Details:

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?
