GetXByBarIndex()

Previous page Return to chapter overview Next page

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

ns

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