AChartEngine高级应用之CombinedXYChart（组合统计图）在单个统计图上显示多样化的数据

现在是信息飞速发展时代，单个的统计图已经无法满足实际生产的要求，人们只想通过快速的观察就能知道很多信息，所以组合统计图就运用而生了，诸如，人们想了解一个地方的大致情况，首先可能要了解当地的天气情况，交通运输情况等，以下我模拟的是一个地方的天气、光照时间分布情况的统计图。这个是AChartEngine图表的高级应用。

构建CombinedXYChart图的步骤主要分为以下三步，还需要在项目中引入AChartEngine依赖jar包，在Manifest中添加：<activityandroid:name="org.achartengine.GraphicalActivity" />

1. 设置XYMultipleSeriesRenderer

XYMultipleSeriesRenderer renderer = new XYMultipleSeriesRenderer();// 设置描绘器

renderer.setAxisTitleTextSize(16);

renderer.setChartTitleTextSize(20);

renderer.setLabelsTextSize(15);

renderer.setLegendTextSize(15);

renderer.setPointSize(5f);

renderer.setMargins(new int[] { 20, 30, 15, 20 });// 上,左,下,右

int length = colors.length;

for (int i = 0; i < length; i++) {

XYSeriesRenderer r = new XYSeriesRenderer();

r.setColor(colors[i]);

r.setPointStyle(styles[i]);

renderer.addSeriesRenderer(r);

}

renderer.setXLabels(12);// X轴均分12项

renderer.setYLabels(10);// Y轴均分10项

renderer.setShowGrid(true);// 显示表格

renderer.setXLabelsAlign(Align.RIGHT);// 右对齐

renderer.setYLabelsAlign(Align.RIGHT);

renderer.setZoomButtonsVisible(false);// 不显示放大缩小

renderer.setPanEnabled(false, false);// 上下左右都不可以移动

//dataset.addSeries(0, sunSeries);

dataset.addSeries(0, waterSeries);

//renderer.addSeriesRenderer(0, lightRenderer);

renderer.addSeriesRenderer(0, waterRenderer);

2. 构建数据源XYMultipleSeriesDataset

// --------------------------曲线start---------------------------------------

String[] titles = new String[] { "最低温度", "最高温度", "平均光照时间" };// 曲线标题

List<double[]> x = new ArrayList<double[]>();

for (int i = 0; i < titles.length; i++) {

x.add(new double[] { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 });

}

List<double[]> values = new ArrayList<double[]>();

values.add(new double[] { -12.3, -8, -2, 3, 16, 18, 26.4, 26.9, 18.6,

12.3, -2, -10 });

values.add(new double[] { 9, 10, 11, 15, 19, 23, 38, 40, 37, 32, 23, 10 });

values.add(new double[] { 6.3, 7.5, 8.5, 9.8, 10.8, 11.3, 13.5, 14.1, 10.3, 9.5, 9.2, 8 });

int[] colors = new int[] { Color.GREEN, Color.RED, Color.YELLOW };// 绿色，红色

PointStyle[] styles = new PointStyle[] { PointStyle.CIRCLE,// 圆圈状

PointStyle.DIAMOND, PointStyle.SQUARE };// 菱形状,矩形状

XYSeries waterSeries = new XYSeries("平均温度");

waterSeries.add(1, -3);// 添加数据

waterSeries.add(2, 6);

waterSeries.add(3, 10);

waterSeries.add(4, 17);

waterSeries.add(5, 20);

waterSeries.add(6, 26);

waterSeries.add(7, 29);

waterSeries.add(8, 30);

waterSeries.add(9, 23);

waterSeries.add(10, 19);

waterSeries.add(11, 10);

waterSeries.add(12, -1);

renderer.setBarSpacing(0.5);

XYSeriesRenderer waterRenderer = new XYSeriesRenderer();

waterRenderer.setColor(Color.CYAN);// 青色

waterRenderer.setDisplayChartValues(true);// 显示数值

waterRenderer.setChartValuesTextSize(10);// 设置数值字体

XYMultipleSeriesDataset dataset = buildDataset(titles, x, values);

//dataset.addSeries(0, sunSeries);

dataset.addSeries(0, waterSeries);

//renderer.addSeriesRenderer(0, lightRenderer);

renderer.addSeriesRenderer(0, waterRenderer);

3. 通过ChartFactory生成CombinedXYChartView组合统计图

mViewChart = ChartFactory.getCombinedXYChartView(

getApplicationContext(), dataset, renderer, types);// 通过ChartFactory生成图表

mLayout.addView(mViewChart, new LayoutParams(LayoutParams.FILL_PARENT,

LayoutParams.FILL_PARENT));// 将图表添加到布局中去

效果图：
