Scrolling does not respect the current magnification level

[GoogleCodeExporter]

If the chart is magnified/zoomed in on, the scrollbars retain their
settings making it impossible to scroll all the way to the right/bottom.

I have the same issue, on the Ubuntu Jaunty's current version as well as latest 
svn
revision 113.
I reported it at launchpad as well:

Scrollbars now reflect zoom levels.

I resolved this by ensuring that the adjustments (ie., the scrollbars) respect 
the
current zoom level. In three places one translates back and forth between 
coordinates
and the values of the adjustments.
