This is an awesome article as almost solved a problem I was facing. I am working on a chart that needs to have the crosshair that doesn’t follow the mouse but follows the actual values on the chart. I am trying to find a neat way of accessing actual pixel values of the Series because it seems like such a waste to do this:

current coordinate -> value @ curr. coordinate -> nearest (actual data) value in series -> coordinate of that value -> pick the coordinate closest to current.

Do you think there could be a more elegant way to do this than just jumping between IRangeAxis.GetValueAtPosition(…) and IAxis.GetPlotAreaCoordinate(…)?

In any case, thanks for a great article!!!

Nice article! Exactly what I was looking for (a usage of GetValueAtPosition).

Sorry Andy, I can’t reproduce your problem. I would advise posting on the toolkit forums:
