Charting widget for GTK or Qt [closed]

Answer 1

How about GTKGraph? Or see if you can pull something out of Grism? The author writes:

I draw stock charts using a GtkDrawingArea and a Cairo context. The charts are not animated, but if you resize the chart window, the chart automatically resizes (actually, it performs a redraw).

Answer 2

There's KD Chart for Qt.

Answer 3

Medsphere has made their graphing widget available, note that it's implemented in gtk# though.

Answer 5

Try this: NightCharts.

But you should keep in mind, that it's a self-made thing without any support and seemingly its development has been stopped already. So probably there may be a plenty of bugs.

And one more thing. IMHO it draws the most pretty pie charts among other Qt chart libraries.
