Example


int applicationPixelY; protected override void OnRender(ChartControl chartControl, ChartScale chartScale) { // Obtain the application-pixel coordinate corresponding to a device-pixel Y value of 500 applicationPixelY = ChartingExtensions.ConvertFromVerticalPixels(500, ChartControl.PresentationSource); }

int applicationPixelY;

protected override void OnRender(ChartControl chartControl, ChartScale chartScale)
{
// Obtain the application-pixel coordinate corresponding to a device-pixel Y value of 500
applicationPixelY = ChartingExtensions.ConvertFromVerticalPixels(500, ChartControl.PresentationSource);
