Hi

I have a graph, in which i have to draw multiple series (7 to 15). which will have more then 50k points for one series.

the problem is that when i add 100k point to one series, qwt plot get really slow.
Re-sizing and zooming function are practically impossible at 500k points.

is there a way to handle this kind of graphs in qwt??

image is a samal example for the kind of graph with one series,
there have to be line series and point series on top of this.
