Definition

Returns the chart-canvas x-coordinate of the bar at a specified index of a specified ChartBars object on the chart.

Note: Since the index is based upon bars that move across the chart canvas as new bars are painted, the value returned by GetXByBarIndex() can be expected to change as new bars are painted on the chart, or as the chart is scrolled backward or forward on the x-axis.

Method Return Value

An int representing a chart-canvas x-coordinate

Syntax

<ChartControl>.GetXByBarIndex(ChartBars chartBars, int barIndex)

Method Parameters

chartBars	The ChartBars object to check
barIndex	The slot index used to determine an x-coordinate

Examples


protected override void OnRender(ChartControl chartControl, ChartScale chartScale) { double xCoordinate = chartControl.GetXByBarIndex(ChartBars, 100); // Print the x-coordinate value Print(xCoordinate); }
