[vtkusers] Smoothing 2D plot in ChartXY

[Yuri Timenkov]

Ah yes, this could make them look differently.

But lines were made thicker because I want to present them on slides, and
thick lines are more visible.

For printing I have another "theme", where lines are thin, but have
different markers or strokes.

I want to reduce the overall detail of picture, because if I have several
graphs on the same picture, the latter becomes complete mess anyways.

Thanks,
Yuri
