Horizontal Cursor for Processbook

Our User requests a "horizontal cursor" for the processbook trend.
(so more or less a rule where also the position in the Y - axis is displayed (transformed) into the scale ...  like the built in vertical curstor)

Since it doesn't seem to happen that we get this change soon...  we like to develop an addin for this.


there are two issues we have:


a)  how do we calculate from the position the value with the right scale
b) and how to best draw the ruler on this screen


for b)  are two options


 -  directly draw into the trend (how can we do this - can we access some kind of canvas ?)
 -  let the user move some kind of ruler (which is a windows forms object) over the screen
