Hello Everyone,

I am starting a new project which require a graph (Curve graph) with its specific features.
I am willing to make it in QGraphicsScene, and i do not want to usw QWT graph api.
Well i have many problems in developing the graph....

1. I have to plot a lot of data in it (Around 3000 - 6000 points)
2. Draw two plots with different axis values (For both plot a new axis is visible behind the current axis. i.e, side by side)

as for the above problems it should have to be fast anc accurate...
Well i am newbie in developing that kind of stuffs., please help me out what will be the structure i follow to create a graph(Curve graph).
and the best way to implement...

THANKS
