scrolling plots & setPos()

[Stefan Seefeld]

Hello,

I'm trying to understand how "scrolling plots" (with the moving x axis) are generated.

The `scrollingPlots.py` example's second plot ("curve2") does (approximately) what I want, but to fine-tune it further I need to understand it a little better. In particular, I'm trying to find documentation of the `setPos()` method that's apparently used to set the x axis origin / range.

That method doesn't appear in the API reference. What is it doing, exactly ?

Thanks,
