Thread Subject: Plots dissapear when using "axes"

Hi everyone!

I have a really odd behaviour of "axes".

I plotted 2 graphs using "plotyy".

[handles.AX1,handles.H1,handles.H2] = plotyy( handles.Signal1TimeVector,...
                                                handles.Signal1,...
                                                handles.Signal2TimeVector,...
                                                handles.Signal2);

handles.AX1 contains the two handles of the axis.

Whenever I call "axes(handles.AX1(n))", one of the graphs keeps dissapearing!!!

Iuse Matlab 2006b.

anyone has an idea?
Thanks
Volker

In Matlab 6.5 the 2nd axis vanishes for "axes(handles.AX1(1))", but for "axes(handles.AX1(2))" both axes are visible. This is exactly what I would expect after inspecting the source of PLOTYY, because this draws the first axis with a white opaque background, while the 2nd axes uses the "Color" 'none'.

Solutions:
1. Either set the "Color" of the 1st axes object to 'none' also.
2. Or even better: do not call "axes(handles.AX1(1))"! If you want to add further objects in the 1st axes, set the according property, e.g.:
  line(1:10, 1:10, 'Parent', handles.AX1(1));
3. If you need a background color, which differs from the fugure's background, you have to create a further axes on the bottom of the others.

Good luck, Jan

Hi Jan!

Thanks for your reply! Still, this drives me crazy!!!!

 I was wondering how I could plot the graphs myself but now I'm slightly confused about the axes.

I want to plot both graphs in an already existing GUI-axes called axes_Signal12.

Any hints?
