曲线图

为长条形状的曲线图：
XYMultipleSeriesRenderer renderer = new XYMultipleSeriesRenderer();
renderer.setAxisTitleTextSize(16);
renderer.setChartTitleTextSize(20);
renderer.setLabelsTextSize(15);
renderer.setLegendTextSize(15);
renderer.setMargins(new int[] {20, 30, 15, 0});
SimpleSeriesRenderer rend = new SimpleSeriesRenderer();
rend.setColor(Color.BLUE);
renderer.addSeriesRenderer(rend);
rend = new SimpleSeriesRenderer();
rend.setColor(Color.GREEN);
renderer.addSeriesRenderer(rend);

renderer.setChartTitle("Chart demo");
renderer.setXTitle("x values");
renderer.setYTitle("y values");
renderer.setXAxisMin(0.5);
renderer.setXAxisMax(10.5);
renderer.setYAxisMin(0);
renderer.setYAxisMax(210);

XYMultipleSeriesDataset dataset = new XYMultipleSeriesDataset();
final int nr = 10;
Random r = new Random();
for (int i = 0; i < 2; i++) {
CategorySeries series = new CategorySeries("Demo series " + (i + 1));
for (int k = 0; k < nr; k++) {
series.add(100 + r.nextInt() % 100);
}
dataset.addSeries(series.toXYSeries());
}

为直线曲线图：
XYMultipleSeriesRenderer renderer = new XYMultipleSeriesRenderer();
renderer.setAxisTitleTextSize(16);
renderer.setChartTitleTextSize(20);
renderer.setLabelsTextSize(15);
renderer.setLegendTextSize(15);
renderer.setChartTitle("雷武情");
renderer.setPointSize(5f);
renderer.setMargins(new int[] {20, 30, 15, 0});
XYSeriesRenderer rend = new XYSeriesRenderer();
rend.setColor(Color.BLUE);
rend.setPointStyle(PointStyle.POINT);
rend.setFillBelowLine(true);
rend.setFillBelowLineColor(Color.WHITE);
rend.setFillPoints(true);
renderer.addSeriesRenderer(rend);
rend = new XYSeriesRenderer();
rend.setPointStyle(PointStyle.CIRCLE);
rend.setColor(Color.GREEN);
rend.setFillPoints(true);
renderer.addSeriesRenderer(rend);
renderer.setAxesColor(Color.DKGRAY);
renderer.setLabelsColor(Color.LTGRAY);

XYMultipleSeriesDataset dataset = new XYMultipleSeriesDataset();
final int nr = 10;
Random r = new Random();
for (int i = 0; i < 2; i++) {
XYSeries series = new XYSeries("Demo series " + (i + 1));
for (int k = 0; k < nr; k++) {
series.add(k, 20 + r.nextInt() % 100);
}
dataset.addSeries(series);
}
跳转显示：
getLineChartIntent() getBarChartIntent()
需要加
<activity android:name="org.achartengine.chartdemo.demo.chart.XYChartBuilder"/>
<activity android:name="org.achartengine.chartdemo.demo.chart.PieChartBuilder"/>
<activity android:name="org.achartengine.chartdemo.demo.chart.PieChartBuilder" />
<activity android:name="org.achartengine.GraphicalActivity" />
这四个Activity。

画出布局：
ChartFactory.getLineChartView().
