On a lot of charts that I build, the default trackball bubble can end up obscuring a lot of the data at the top of the chart. Is there a way to move the trackball to the bottom of the chart or set it's opacity so that the series can partially bleed through?
You can hide the trackball control and display only the trackball line over your items. The information that goes into the trackball can be presented somewhere outside the control. Here is some code:
I use the TrackInfoUpdated event to append the info to the items in my chart legend. It would be good if the TrackInfoUpdated event could also be raised when the track ball line is hidden when the user moves the mouse out of the chart indicating that the track ball line is now hidden so that I can hide the info from the chart legend. Currently the chart legend will continue to show the values from the last time the TrackInfoUpdated event was raised.

Hello Remco,
Indeed, this behavior seems strange. I have logged it in our bug tracking system here. You can expect a fix for the Q2 release.
