Examples


protected override void OnRender(ChartControl chartControl, ChartScale chartScale) { // Store the beginning and ending x-coordinates of the canvas area double canvasBeginCoordinate = chartControl.CanvasLeft; double canvasEndCoordinate = chartControl.CanvasRight; // Print the stored values Print(String.Format("Chart canvas begins at x-coordinate {0} and ends at x-coordinate {1}", canvasBeginCoordinate, canvasEndCoordinate)); }

protected override void OnRender(ChartControl chartControl, ChartScale chartScale)
{
// Store the beginning and ending x-coordinates of the canvas area
double canvasBeginCoordinate = chartControl.CanvasLeft;
double canvasEndCoordinate = chartControl.CanvasRight;

// Print the stored values
Print(String.Format("Chart canvas begins at x-coordinate {0} and ends at x-coordinate {1}", canvasBeginCoordinate, canvasEndCoordinate));
}

Based on the image below, CanvasLeft reveals that the chart canvas area begins at x-coordinate 53.

ChartControl_CanvasLeft

Note: When no data series are left-aligned on a chart, CanvasLeft will return 0, representing the x-coordinate origin, because the chart canvas will begin at coordinate 0.
