"hold on" equivalent in GUIDE

Hello all,

When I update my plot in GUIDE, the imline lines that were previously defined disappear. Is there a way to make them permanent by using an equivalent of "hold on"? Or do I have to re-plot, everything, every time I change something to my plot? Thank you in advance!

Have you tried using drawnow command?

What do you mean by 'when I update my plot in GUIDE'? GUIDE is just a GUI design tool, it doesn't run anything or include plots in it.

Just to clarify, I had my imline plotted on some axes, then I would plot an image on these axes, and my imline would "disappear". It turns out that it was still there, only hidden behind the image.

Adding something like

uistack(imline_handle,'top')

solved it!

Thank you all for your help!

My point holds for imline as well. You can specify a parent, so you should. Not specifying parent objects in GUIs will cause problems at some point that you will not be able to debug. It is a pain, but it is a vital step in finalizing code. Alternatively, you can force the axes to be the current axes with axes(handles.ax).

You should always specify the axes you want to affect, so you can use hold(handles.ax,'on').

GUIDE is just a shell around 'normal' Matlab, so anything that works as a function should work in a function created by GUIDE as well.
