Get clicked data point or axis position otherwise
posted

Hi.

I'm have a chart showing points over time using CategoryDateTimeXAxis.

I want to get the following behavior:

if user click on a series data point, the application should identify that and do something (let's say show a message box with the x and y values)

else show the y value, converted to datetime.

I have the following code that give me the y value based on the axis, but how can I get the first request also?

private void timeline_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
     {
         MoveNavBar(e);
     }
 
     private void MoveNavBar(MouseEventArgs e)
     {
         if (e.LeftButton == MouseButtonState.Pressed)
         {
             var position = e.GetPosition(axisX);
 
             //we 
 
             var x = timeline.Axes.OfType<CategoryDateTimeXAxis>().First();
             var viewport = new Rect(0, 0, x.ActualWidth, 0);
             var window = timeline.WindowRect;
 
             ScalerParams sp = new ScalerParams(window, viewport, false);
             var unscaledX = x.GetUnscaledValue(position.X, sp);
             DateTime selectedTime = new DateTime((long)unscaledX);
 
             NavigationController.SetDate(selectedTime, this);
         }
     }
