My program should work in such a way there's a button that we can click. And everytime I click it, it should update a graph in another form. How do I do that? Because right now, everytime I click it, it only opens the form as for now, the only codes I've put in under the clickevent of the button is : Audiogram.Show() 'Audiogram is the other form. Is there any codes for the clickevent method that I can use to make the button able to update the Audiogram form with every click? Thank you.

Yes, it shows the correct graph. However the previous point plotted disappear and it just plots the new point.
