Hello,

I have a program that displays the output of a sensor device in real time. It uses normal GDI calls to display a line plot of the incoming data. It works fine, but there is a great deal of flicker in the image as it is being updated. What is the best way to reduce this flicker (I guess my real question is how does one do graphical output when the graph is changing rapidly, like in a data acquisition application)? Should I be using OpenGL or something?


Thanks!
