我尝试将另一组值添加到stacked bar charts with achartengine的演示示例中，但我引入的新值不会显示在图表上。堆叠条限制为两个柱？
public Intent getIntent(Context context) {
String[] titles = new String[] { "Good", "Defect", "Repair" };
List<double[]> values = new ArrayList<double[]>();
values.add(new double[] { 14230, 12300, 1424, 15240, 15900, 19200,
22030, 21200, 19500, 15500, 12060, 14000 });
values.add(new double[] { 14230, 12300, 14240, 15244, 15900, 19200,
22030, 21200, 19500, 15500, 12600, 14000 });
values.add(new double[] { 5230, 7300, 9240, 10540, 7900, 9200, 12030,
11200, 9500, 10500, 11600, 13500 });
int[] colors = new int[] { Color.GREEN, Color.YELLOW, Color.RED };
XYMultipleSeriesRenderer renderer = buildBarRenderer(colors);
setChartSettings(renderer, "Machine Efficiency Rates",
"Machine", "NET produce", 0.5, 12.5, 0, 24000, Color.GRAY,
Color.LTGRAY);
renderer.getSeriesRendererAt(0).setDisplayChartValues(true);
renderer.getSeriesRendererAt(1).setDisplayChartValues(true);
renderer.getSeriesRendererAt(2).setDisplayChartValues(true);
renderer.setXLabels(12);
renderer.setYLabels(5);
renderer.setXLabelsAlign(Align.LEFT);
renderer.setYLabelsAlign(Align.LEFT);
renderer.setPanEnabled(true, false);
renderer.setZoomEnabled(true);
renderer.setZoomRate(1.1f);
renderer.setBarSpacing(0.5f);
return ChartFactory.getBarChartIntent(context,
buildBarDataset(titles, values), renderer, Type.STACKED);
}

AChartEngine显示堆积条形图的方式存在误解。它并没有真正堆叠它们，而是将它们一个显示在另一个上面。这意味着您需要始终先添加较大的值，然后再将较小的值添加到第一个系列，第二个在第一个系列之上，依此类推。
更新：从版本1.2.0开始，有新的HEAP堆积条形图，以您需要的方式显示。

我找不到一个好的答案。但是，您可以使用getCombinedXYChartIntent 创建多个堆叠条。
我使用CombinedTemperatureChart作为模板并进行了修改以实现此目的。

我希望有人仍然需要这个，需要一段时间来弄明白。 不幸的是，我没有点粘贴图像。
