Android平台上的AchartEngine可以制作折线图、曲线图、直方图、饼图等等的图标，本文是爱站技术频道小编带给大家的Android开发中如何使用achartengine绘制各种图表，一起进入下文学习吧！

分享给大家供大家参考，具体如下：

1. ABarChart.java

import java.util.Random;
import org.achartengine.ChartFactory;
import org.achartengine.chart.BarChart.Type;

    // TODO Auto-generated method stub
    XYMultipleSeriesRenderer renderer=new XYMultipleSeriesRenderer();

    r=new SimpleSeriesRenderer();
    r.setColor(Color.BLUE);
    renderer.addSeriesRenderer(r);
