Re: qwt plot and scrollbars

[Darryl W. <dar...@pr...>]

Check out the realtime plot example that comes with Qwt.  It shows how 
to make a "ScrollZoomer" but that may help point you in the right direction.

It'd be kind of a hack but you could implement the scrollzoomer, and 
then when your data is added you can update the zoomRect.  Or something 
along those lines.
