ChartArea

Class Overview

Represents chart area class. Chart area is an integral part of ChartEngine. It handles series and axes drawing logic. By design, chart passes recursive draw and layout calls to its children. Parent ChartEngine is able to host several areas represented by areas collection. Legend may represent series from separate areas making possible complex layout design depending on desired output (i.e. couple pie charts with legend representing each of them).

 // Retrieving default ChartEngine from ChartView
 Chart chart = chartView.getChart();
 // Adding 3 pie areas to the chart.
 for (int i = 0; i < 3; i++)
 {
 	// Instantiating ChartArea.
 	ChartArea area = new ChartArea();
 	// Setting the area name
 	area.setName("area" + i);
 	// Adding new area to chart.
 	chart.getAreas().add(area);
 
 	// Instantiating ChartSeries.
 	ChartSeries series = new ChartSeries("Series" + Integer.toString(i),
 			ChartTypes.Pie);
 	// Caching points collection.
 	ChartPointCollection points = series.getPoints();
 	// Adding 10 points to series.
 	for (int j = 0; j < 10; j++)
 	{
 		points.addXY(j, j * 100);
 	}
 
 	// Wiring series with area
 	series.setArea(area.getName());
 	// Adding series to chart.
 	chart.getSeries().add(series);
 }
