Hello! I use Nevron Chart for WPF. How I can transform mouse coordinates to chart axis coordinates? This code is incorrect, because WPF ChartControl does not contain View method
private void _chartControl_MouseDown(object sender, System.Windows.Input.MouseButtonEventArgs e)
{
System.Windows.Point point = e.GetPosition(_chartControl);
NCartesianChart chart = (NCartesianChart)(_chartControl.Charts[0]);
NViewToScale2DTransformation transf = new NViewToScale2DTransformation(_chartControl.View.Context, chart, (int)StandardAxis.PrimaryX, (int)StandardAxis.PrimaryY);
NVector2DD pointScale = default(NVector2DD);
transf.Transform(new NPointF((float)point.X, (float)point.Y), ref pointScale);
}
Thanks

Hi Vladimir, We just tested with a recent version (19.7.15.12) and the WPF control did have a View method - what is the version you're currently testing with?

Hi Vladimir, Also this code applies to Nevron Chart for .NET, not NOV Chart - do you want to perform coordinate transformation in the NOV Chart or the .NET Chart?
