How to refresh the screen so that closed forms virtually disappear

I have several forms that appear during an intensive operation. For example, when a form pops up asking for something from the user and the user clicks OK, the chart form remains on the main screen, even if it is closed. How can I make it so that these graphs completely disappear?

I would recommend doing heavy work in the background (e.g. BackgroundWorker), so the GUI thread is not blocked. Thus, the forms will be able to display screen updates during operation.

You can call the Refresh () method in the form of the main screen, which will cause the graphics to repaint.
