Hello!

I’m trying to draw several plots on after the other in a wxScrolledPanel but I got the error message:

Has someone an idea how to solve this?

Thank in advance

Hello Stefanie,

I think the problem is that you try to initialise a subplot with
subplot(112)
which is not possible, because the first to numbers in 112 define the subplot
structure / geometry (here 1 by 1) and the last number give the index of the
subplot.
In general you could use N x M (N rows and M columns) for subplots by
subplot(N,M,index)
where 'index' would be a number between 1 and N * M.

best regards Matthias
