Need help in WPF Chart control to map Mouse Coordinates to Y Axis
posted

I would appreciate if someone could point me how to map mouseCoordinates to Y Axis. I know For Ultrachart there is a call AxisY.MapInverse() but for WPF control i could not find it.

 

I am trying to implement drag and drop of scatter points by MouseDown/ MouseMove/ MouseUp and using Chart.HitTest(e). Most of the code works. Just on MouseUp i need to know the new coordinates in Y Axis.

 

thanks

    You don't need to use MapInverse(), you have the coordinates mapped to the axes.

    private void XamChart_MouseLeftButtonUp(object sender, MouseButtonEventArgs e)

    {

    HitTestArgs args = Chart.HitTest(e);

    double yAxisValue = args.YValue;

    double xAxisValue = args.XValue;

    }
