Qt graphics

[ShaChris23]

Hi guys,

I have a scientific application that currently uses the following library to display acoustic data image in 2D ( expressed as 32-bit complex floating point values; i.e. they take lines of floating point values and display it as an image on the screen. )

http://www.codeproject.com/miscctrl/graph2d.asp

I would like to replace the existing library with Qt. In particular, it would be nice if I could offload the 2D drawing onto a graphics card instead. Can somebody point me out to me where I can read up more on this topic?

Thanks!

You could try Qwt (http://qwt.sf.net).
