Class ChartHiLoOpenCloseType

java.lang.Object com.artfulbits.aiCharts.Base.ChartType com.artfulbits.aiCharts.Types.ChartHiLoOpenCloseType

Declaration: public class ChartHiLoOpenCloseType extends com.artfulbits.aiCharts.Base.ChartType

 

Represents HiLo Open Close chart type. A HiLo chart combines two independent values to supply high and low data for each point in a series. HiLo charts are used primarily in financial applications to show the high and low price for a given stock. The elements of the Y values array in each series' point of a HiLo chart represent the "high" value, and the "low" value.
 ChartSeries series = new ChartSeries("Series 1", ChartTypes.HiLo);
 // Filling series with 10 data points.
 for(int i = 0; i < 10; i++)
 {
 	//Supplying Hi and Low values.
 	series.getPoints().addXY(i, Math.cos(i) - 1, Math.cos(i) + 1);
 }
 
* Similar output should be expected:

HiLo type uses LowValue and HighValue types to determine index of corresponding Y values among chart point's Y values.
