使用Achartengine可以实现多个堆叠条形图吗？

我尝试将另一组值添加到带有achartengine的堆积条形图的演示示例中，但我引入的新值不会出现在图表上。 堆叠条限制为两个吧？

public Intent getIntent(Context context) { String[] titles = new String[] { "Good", "Defect", "Repair" }; List values = new ArrayList(); 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); } 

Answer 1

AChartEngine显示堆叠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，然后将较小的值添加到较小的值，依此类推，因为它呈现第一个系列，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。

最初的原始代码是这样的

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。
