GUIDE: findobj() results in handle to deleted Line

Hi All,

I'm trying to extract line information from two different plots in GUIDE. My approach is to plot the first -> save it into base workspace -> switch axes -> plot the second -> save it into base workspace

Once this is done, I then tried to check if this works using the following function:

a = findobj(handles.axes1, 'Type', 'Line')

b = findobj(handles.axes2, 'Type', 'Line')

b does give a result, however a would give the following error:

'handle to deleted Line'

Any idea for any workaround?

Thanks!

It makes sense that the practice has a name. Good to know it now, thanks.
