If in the Chart > Data Ranges... window the preview would take more than 5 seconds to draw, then make a question about whether you want the preview.
If I am using thousand of data points and accidentally select a wrong configuration in that window, then the program starts operations that takes mintues to finish.
In this case, the program should ask whether I want to wait that much for a live preview, or just continue editing the window contents.

Yes, the issue is slow preview and this is one solution and the other is the checkbox.
