In Excel 2003 I used scroll bars to set the limits on a dynamic range
of my chart. Basically, I used to "zoom in" on a particular section of
the chart. The chart would be instantly updated as I adjusted the
scroll bars. I am using the same method in 2007 but in this case the
chart is only updated when I release the mouse button. Am I stuck with
this type of performance or is there a setting I can change?
