LightningChart Support Forums

Hi. I have a chart with 3 freeform point line series (image below).

I have a LineSeriesCursor enabled as well, and the trackpoints do not track correctly at all. Am I missing something? The trackpoints are all over the place.

Thanks!

Hi Greg,

I'm sorry to say, LineSeriesCursor supports only series than inherit from ITrackable. FreeformPointLineSeries is not such.

Instead, please use freeformPointLineSeries.SolveNearest*** methods to find the nearest data point by mouse coordinate or given X,Y point.

I think for right now i'm just going to turn off 'point tracking' while im using FreeformPointLineSeries. My graphing package can toggle between linear axis (uses sampledataseries) and XY plotting (freeform point line series).

When I come back to this issue, i'll probably use Series Event Markers to drop those points back in.

Thanks for the help
