    Mouse to SharpDX coordinates

    I created a proof of concept indicator that can be clicked on to highlight - attached. I am doing something wrong with mouse pointer to WPF coordinates because there's a discrepancy where mouse pointer clicks and where it 'registers'. The discrepancy seems linear and increases the further away the click is from 0,0.

    I figured it out: use built-in coordinate transformation methods:

    float deviceX = ChartingExtensions.ConvertToHorizontalPixels(wpfCl ickPosition.X, ChartControl.PresentationSource);
    float deviceY = ChartingExtensions.ConvertToVerticalPixels(wpfClic kPosition.Y, ChartControl.PresentationSource);​

      Hello MiCe1999,

      Likely you have the windows text size at a value greater than 100 which is causing the discrepancy. (DPI)

      See the example on the forum linked below which adjusts.
