GUI picture is already loaded in axes when GUI opens
显示 更早的评论
I have a GUI that pulls images from a url then displays them in a figure with data plotted on top. The issue is, everytime I open the GUI, without interacting with any of the buttons, etc. there is already an image loaded in the axis fromm a previous time I used the program.
It doesn't update everytime I use the program, the image that preloads is one from a while ago and its always that image that loads. I though it midght have been a set handles error, but I don't see one.
I can add code if needed, but I wasn't sure if anyone else had already had this problem.
Thanks a bunch!

Does it open with the image if you've close MATLAB between sessions?

In the gui_OpeningFcn, put:
cla
reset(gca) % Should undo the zoom.

Chris says,
Okay, that helped with the first issue. The reason that I was having difficulties was that the previous image that loaded was automatically zoomed in on the top left hand corner. When I loaded a new image, this image was also zoomed in on the top left corner automatically and not all of the image was put into the figure. However, when I create a new figure in the command prompt and run through all of the code again in the debugger everything works perfectly.
I hope that explanation makes sense.

See the additional command in my suggestion.
