Follow-up Comment #3, bug #30509 (project octave):
I get the following output:
>> plot(1:100,'c');
>> hold on;
>> get (gca, 'ydir')
ans =
normal
>> imshow ('arrow_up.jpg')
Warning: The image file directory at offset position 38 has zero entries and
has been ignored.
>> get (gca, 'ydir')
ans =
reverse
The figure shows the image (arrow pointing up), but not the plot. Basically,
when you show an image the figure is reset. So, when you want a figure
containing both an image and a plot you need to show the image first and then
make the plot.
