Hello, I am developing a gui in which I have given the push button and some inputs. After pressing push button plot will generate on the axes of the gui but the problem is occurring in the next step when I will again put the new value in the input then the plot is being overwrite by the old plot. How can I remove the old plot after putting the new inputs?

Thanks

If you want to clear all existing plots when you next press the button you need to put

hold( handles.plotAxes, 'off' )

at the start. Or

cla( handles.plotAxes )

if you use

hold on

every next (new) plot will added to the old plot, so both/ all plots will be shown.

to deactivate adding plots use hold off (documentation of hold)

hold off % default option, only need to use if you used hold on before

so that every new plot automatically deletes the old one
