Example


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

int devicePixelY;

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