[vtkusers] Smoothing 2D plot in ChartXY

Hello,

I have a raw set of 2D data from vtkTable using new vtkChartXY API (function
in time). But it has a lot of peaks and falls and too much details (see
example in attachment). I want to make it look niceer, so I see 3 options:

   1. Draw every Nth point.
   2. Reduce number of points my averaging adjacent values.
   3. Draw kind of envelope.

Does VTK provide any means to do it automatically or I have to prepare data
somehow before plotting?

Thanks in advance,
Yuri
