Is there code/add-in to lines with a mouse on a chart???

[TheNinja]

I am a semi decent excel/vba user. Right now I have pressure data and its derivative data plotted on a log-log graph. There are three "trend" lines also plotted that solves for different points. I am using scrolling bars to move the lines. I was wondering if there was code or and add-in that would allow the user to move the lines with the mouse instead of the scroll bars. The solved points are used in calculations to estimate wellbore properties. Thanks.

I think it would be very difficult to code using mouse movement.

The chartobject can react to mouse events but you will have a devil of a time trying to work the scaling out.

Maybe just using controls that allow for interactive updating of the chart will do.
