public class BarChart
extends Chart

This bar chart component enables you to add a bar chart to your java applications with just a few lines of code.

A simple bar chart can be created with the following code:

 BarChart chart = new BarChart(5);
 long[] values = new long[] {100, 200, 300, 400, 500};
 chart.setSampleValues(values);

A chart with the legend turned on, multicolor set, and displayed in 3D can be created with the following code:

 BarChart chart = new BarChart(5);
 long[] values = new long[] {100, 200, 300, 400, 500};
 chart.setSampleValues(values);
 chart.setMultiColorOn(true);
 chart.setLegendOn(true);
 chart.set3DModeOn(true);

See here for a list of parameters to set for the bar chart.
