OpenGl and QT Creator Stripchart
Linux and OpenGL novice
My goal is to write a simple strip chart viewer. I can get the data but need the method to display it. The suggestion is to use OpenGL and maybe run it under/within QT Creator. I have found very little on this.
Any suggestions as to where to look?
Edit
No one else has replied so narrow the scope a bit.
Is there a way to move a rectangle of pixels displayed on the screen? Move them one or some number of pixels to the left or right, or maybe up or down?
Details, just in case: a strip chart is displayed as a 2D array of pixels. Rather than clearing and redrawing for each data point I would rather move the array a little bit and add the new points.
All this using Open GL.

Wiki said that is a command line program. We need a plot than can run within the C++ environment.
Did not know about gnuplot so thanks for the info.

I'm not really understand your question, but this article show to how draw line with OpenGL
