I'm attempting to make a custom overview with pan/zoom scroll bar. The problem is, the data in the chart is not the total viewable amount of data (which I have stored in my own buffers) so I need to control the drawing manually. I have this working using textboxes, I have a start point and an end point which causes my primary chart surface to zoom out to the range specified from my buffers.
Now I need to bind these integer properties to the grips of the scroll bar, but it seems if you don't bind them to the chart's axis they send you to a break mode. I don't want the scroll bar directly bound to an axis on the chart, is this not possible?
