Different types of plots in the same uipanel

Hi,

I am going between a single plot and multiple subplots plots in the same uipanel of a GUI I am creating. A value in a popupmenu determines the type of plot to graph. I've created the GUI using 'guide' and I have placed an axes in the desired uipanel.

The problem is, when I switch between the single plot and the subplots, it seems that I am clobbering my axes object. If I display all of the handles in the command window, the axes handle is displayed until I select to option to plot the subplots. If I go back to the single plot, I receive an error that says 'Invalid Handle Object' and the axes handle disappears from the list of handles.

Does the function subplot clobber the current axes object? Does anyone know why my axes handle is disappearing when the function subplot is called?

Thanks for your help!

Yes, just as it is documented to do.

>> help subplot

    If a SUBPLOT specification causes a new axis to overlap an
    existing axis, the existing axis is deleted - unless the position
    of the new and existing axis are identical. For example,
    the statement SUBPLOT(1,2,1) deletes all existing axes overlapping
    the left side of the Figure window and creates a new axis on that
    side - unless there is an axes there with a position that exactly
    matches the position of the new axes (and 'replace' was not specified),
    in which case all other overlapping axes will be deleted and the
    matching axes will become the current axes.

Hi Walter,

Thank you for the reply! The function subplot seems to be getting in the way with what I am looking to do. Is there a better way of doing this? I could possibly create two different axes over one another. If I wanted to plot the single bar plot, I could display it on axes1 and make axes2 invisible. If I wanted to plot multiple pdf plots, I could call subplot and display it on axes2 and make axes1 invisible.

This seems problematic, because when I call subplot, it is still going to erase axes2, correct? Is there a way to do this so I don't loose my axes and can reuse it over and over with each different type of plot?

Thanks for your help!!
