Example


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

int devicePixelX;

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