Flickerless Graphics Problem

Question

I'm using SetStyle(ControlStyles.UserPaint | ControlStyles.AllPaintingInWmPaint |ControlStyles.DoubleBuffer true) to create flickerless drawing in a custom graph control I'm using. Everything works great except that when another window passes over the control the invalidated area isn't being redrawn correctly. Has anyone else encountered this problem?

I would suggest looking at VanCharts . It's a free library for making visual charts. It supports data display in the web (JavaScript) and mobile terminals (Android native/iOS native/Webview) and provides various types of common commercial charts.
