display large data on graph

[Ohad]

I'm using the CWGraph control and trying to display large plots (more then 100,000 values). whenever I do so the graph responses become very slow and render it unusable. Is there any way you can recomend that might improve the situation? Any program code?

Hello Ohad,

I cannot replicate your problem of having "graph responses become very slow". Please try out the attached code. I modified the Measurement Studio shipping example "Plots vs Charts" to plot/chart 100,000 values. It does not become slow or unresponsive when plotting or charting (as long as you plot/chart entire vectors and not individual points!).
