Question

我无法在反转图表视图上设置标签。我正在为图表使用MPchart库。我必须显示带有标签的倒置图形，并根据值在顶部排列。我无法在X轴上设置标签。

我希望我的图表看起来像这样。但是我无法在每个图形上显示标签和编号。

我得到的是什么

这是我的代码：

   ArrayList<BarEntry> bargroup1 = new ArrayList<>();
    bargroup1.add(new BarEntry(12f, 4));
    bargroup1.add(new BarEntry(16f, 2));
    bargroup1.add(new BarEntry(20f, 1));
    bargroup1.add(new BarEntry(24f, 3));
    bargroup1.add(new BarEntry(28f, 5));

    ArrayList<BarEntry> bargroup2 = new ArrayList<>();
    bargroup2.add(new BarEntry(13f, 4));
    bargroup2.add(new BarEntry(17f, 2));
    bargroup2.add(new BarEntry(21f, 1));
    bargroup2.add(new BarEntry(25f, 3));
    bargroup2.add(new BarEntry(29f, 5));


    BarDataSet barDataSet1 = new BarDataSet(bargroup1, "");


    barDataSet1.setColors(getResources().getColor(R.color.app_logo_color));

    BarDataSet barDataSet2 = new BarDataSet(bargroup2, "");

    barDataSet2.setColors(getResources().getColor(R.color.app_grey_color));

    final ArrayList<String> labels = new ArrayList<String>();

    labels.add("Buy");
    labels.add("Over");
    labels.add("Hold");
    labels.add("Under");
    labels.add("Sell");

    dataSets = new ArrayList<>();

    datasetdemo = new ArrayList<>();

    dataSets.add(barDataSet1);

    dataSets.add(barDataSet2);

    YAxis yAxisRight = barChart.getAxisRight();
    yAxisRight.setEnabled(false);
    YAxis yAxisLeft = barChart.getAxisLeft();
    yAxisLeft.setEnabled(false);

    // or use some other logic to save your data in list. For ex.

    XAxis xAxis = barChart.getXAxis();
     xAxis.setEnabled(false);
    xAxis.setEnabled(false);
    xAxis.setDrawGridLines(false);
    barChart.invalidate();
    barChart.setScaleEnabled(false);
    barChart.getXAxis().setDrawGridLines(false);
    barChart.getAxisLeft().setDrawGridLines(false);
    barChart.getAxisRight().setDrawGridLines(false);

    xAxis.setValueFormatter(new IndexAxisValueFormatter(labels));

    BarData data1 = new BarData(dataSets);

    barChart.setData(data1);

我必须在每个栏的顶部显示标签和数字数据。

这是您要实现的图形的解决方案：（下面的代码允许您对条形进行分组，图形反转，以及在图形反转时在垂直条下方显示标签）

我创建了自己的“ BarChartRendererMine”类，我们将需要在倒置的垂直条下方显示标签。因此，创建“ BarChartRendererMine”类并复制以下代码：

        barChart.setRenderer(barChartCustomRenderer);
        xAxis.setAxisLineColor(getResources().getColor(R.color.colorTransparent));


    }

}

这将更改线条颜色，看起来像是隐藏的

"xAxis.setAxisLineColor(getResources().getColor(R.color.colorTransparent));"

自定义绘制条形图所需的以下线条：

BarChartRendererMine barChartCustomRenderer = new BarChartRendererMine(barChart, barChart.getAnimator(), barChart.getViewPortHandler());
barChart.setRenderer(barChartCustomRenderer);

希望它会有所帮助：）
