参考官网：https://code.google.com/p/achartengine/

                <activity android:name="org.achartengine.GraphicalActivity" />

public void test() {//准备数据集XYMultipleSeriesDataset dataset = new XYMultipleSeriesDataset();Random r = new Random();for (int i = 0; i < 2; i++) {XYSeries series = new XYSeries("test" + (i + 1));for (int k = 0; k < 10; k++) {series.add(k, 20 + r.nextInt() % 100);}dataset.addSeries(series);}//准备渲染器XYMultipleSeriesRenderer renderer = new XYMultipleSeriesRenderer();XYSeriesRenderer xyRenderer = new XYSeriesRenderer();xyRenderer.setColor(Color.BLUE);xyRenderer.setPointStyle(PointStyle.SQUARE);renderer.addSeriesRenderer(xyRenderer);XYSeriesRenderer xyRenderer1 = new XYSeriesRenderer();xyRenderer1.setColor(Color.RED);xyRenderer1.setPointStyle(PointStyle.CIRCLE);renderer.addSeriesRenderer(xyRenderer1);//使用内置Activity用于显示Intent intent = ChartFactory.getLineChartIntent(this, dataset, renderer);startActivity(intent);}
