Hi. I have a line series displayed on a chart. I've subscribed to the MouseClick event of the NChartControl instance. When I get the event handler invoked, I perform a HitTest which returns a NHitTestResult object. I want to know somehow if the user clicked the line or the marker point. Is there a way to get such a distinction?
Thanks in advance, Alexander Efimov.

Hi Alex, The line series will record markers and line segments as visual elements that belong to a "data point". In general all series behave like this as the lowest "precision" of the internal image map in the chart is data point - therefore the chart cannot distinguish if the item clicked is a line segment or a marker. You can easily workaround this limitation by using a second point series with the same values as the line series instead of using markers.
