Hello,
I'd like to get some suggestions on the best way to accomplish putting annotations on an XYPlot.
I have an XYPlot with two lines (series).
The user should be able to use the mouse to select a point on one series.
Then I want to draw a vertical line from the point on the selected series to the other series.
And also draw a horizontal line from the point on the selected series to other series.
I then need to label both the vertical line and the horizontal line giving information about the difference in values at the endpoints of the lines.
Any suggestions on how best to approach this would be appreciated. For example, which Annotation class would be best and how to best detect a mouse click on a series and to get the series value at that point.
Thank you.
