Real Time plots

[<ala...@pa...>]

Hi,

I am looking at a graphics 2D library for displaying real time data on pl=
ots. I looked at qwt, but I found that at every plot update all plots are=
 redrawn, and not just 1 point is being added, since qwt uses the polygon=
 mechanism. Is there a possibility to just add 1 point instead of having =
to redraw everything all the time?

Tx
