如何使用条形和线条创建CombinedChart？

Question

我正在使用MPAndroidChart。如何在组合图表中创建多部分条形图系列，我将条形图和折线图组合在一起

这是我的代码，请看看

   private BarData generateBarData(List arrayList){
        ArrayList<BarEntry> barEntries = new ArrayList<BarEntry>();
        BarData barData = new BarData();
        for(int counter=0;counter<arrayList.size();counter++)
        {
            barEntries.add(new BarEntry(20.0f,counter));
        }

        BarDataSet barDataSet = new BarDataSet(barEntries,"Bar Dataset");
        barDataSet.setColor(Color.rgb(60, 220, 78));
        barDataSet.setValueTextColor(Color.rgb(60,220,78));
        barDataSet.setValueTextSize(10f);
        barData.addDataSet(barDataSet);
        barDataSet.setAxisDependency(YAxis.AxisDependency.LEFT);
        return barData;
    }
private LineData generateLineData(ArrayList arrayList){
        ArrayList<Entry> lineEntries = new ArrayList<Entry>();
        LineData lineData = new LineData();
        for(int counter=0;counter<arrayList.size();counter++)
        {
            lineEntries.add(new Entry(20.4f,counter));
        }
        LineDataSet lineDataSet = new LineDataSet(lineEntries,"Line Dataset");
        lineDataSet.setColor(Color.rgb(240,238,70));
        lineDataSet.setLineWidth(2.5f);
        lineDataSet.setCircleColor(Color.rgb(240, 238, 70));
        lineDataSet.setCircleSize(5f);
        lineDataSet.setFillColor(Color.rgb(240, 238, 70));
        lineDataSet.setDrawCubic(true);
        lineDataSet.setDrawValues(true);
        lineDataSet.setValueTextSize(10f);
        lineDataSet.setValueTextColor(Color.rgb(240, 238, 70));
        lineDataSet.setAxisDependency(YAxis.AxisDependency.LEFT);
        lineData.addDataSet(lineDataSet);
        return  lineData;
    }

在CombinedChart中， v3.0.0 之前的版本不支持多个BarDataSets。

自release v3.0.0起，CombinedChart支持多个小节。
