Hi all,
I am trying to get used to the new App Designer.
I am having the issue that when running the App Designer with an axes plot (Axis_1), the code runs fine, but I get a seprate empty figure out of the GUI.
plot(app.Axis_1,ff,av_power(:,:),'k','LineWidth',2)
hold on
plot(app.Axis_1,ff,power(:,:),'r','LineWidth',1);
Any help much appreciated
Thanks

Specify the axis handle
hold(app.Axis_1,'on')
