Hi Walter
Thanks a lot for your reply, this was very helpful. However, the refreshdata method doesn’t seem to work with multiline plots.
%% Example: y = rand(100,3); h = plot(y); set(h,'YDataSource','y'); pause(1) y=y(1:10,:); refreshdata(h); >> ??? Error using ==> refreshdata at 58 >> Could not refresh YData from 'y'.
How can this be and is there a way to work around it?
Regards Markus
