ToIndex

Definition

An index value representing the last bar rendered on the chart. See also FromIndex.

This value is NOT the last value that exists on the ChartBars, but rather the last bar index that is within the viewable range of the chart canvas area. This value changes as the user interacts with the ChartControl time-scale (x-axis).

Property Value

An int representing the last bar index painted on the chart.

Syntax

ChartBars.ToIndex

Examples

1 protected override void OnRender(ChartControl chartControl, ChartScale chartScale)
2 {
3    if (ChartBars != null)
4    {
5      // loop through all of the viewable range of the chart
6      for (int barIndex = ChartBars.FromIndex; barIndex <= ChartBars.ToIndex; barIndex++)
7      {
8          // print the High value for each index within the viewable range
9          Print(High.GetValueAt(barIndex));
10      }
11    }
