MPandroid x轴标签与条形图不对齐

Question

我的x轴值没有对齐。我应该修改什么设置？

x轴未对齐

下面是我到目前为止在代码中使用的。setLabelsToSkip将无法工作，因为我使用的是3.0.1版。

XAxis xAxis = mChart.getXAxis();
    xAxis.setTypeface(mTfLight);
    xAxis.setGranularity(1f);
    xAxis.setCenterAxisLabels(true);
    xAxis.setDrawLabels(true);
    xAxis.setGranularity(1f);
    xAxis.setGranularityEnabled(true);
    xAxis.setPosition(XAxis.XAxisPosition.BOTTOM);
    xAxis.setTextColor(Color.WHITE);
    xAxis.setTextSize(15);

这是我的标签格式化程序类：

import com.github.mikephil.charting.components.AxisBase;
import com.github.mikephil.charting.formatter.IAxisValueFormatter;

public class LabelFormatter implements IAxisValueFormatter {
private final String[] mLabels;

public LabelFormatter(String[] labels) {
    mLabels = labels;
}

@Override
public String getFormattedValue(float value, AxisBase axis) {
    return mLabels[(int) value];
}
}

以下是我的主要活动setdata方法：

    private void setData() {
    ArrayList<BarEntry> entries = new ArrayList<>();
    String labels[]=new String[5];
    for (Cars c : values) {

       if (c.getX()==1){
            labels[0] = "Engine 1";
        }
        if (c.getX()==2){
            labels[1] = "Engine 2";
        }
        if (c.getX()==3){
            labels[2] = "Engine 3";
        }
        if (c.getX()==4){
            labels[3] = "Engine 4";
        }
        if (c.getX()==5){
            labels[4] = "Engine 5";
        }

        entries.add(new BarEntry((float) c.getX(), ((float) c.getY()),labels));

    }
    BarDataSet set1;

    if (mChart.getData() != null && mChart.getData().getDataSetCount() > 0) {
        set1 = (BarDataSet) mChart.getData().getDataSetByIndex(0);
        set1.setValues(entries);

        mChart.getXAxis().setValueFormatter(new IndexAxisValueFormatter(labels));
       //set1.setValueFormatter(new LabelFormatter(labels));
       //mChart.getXAxis().setValueFormatter(new BarValueFormatter(set1));
        mChart.getData().notifyDataChanged();
        mChart.notifyDataSetChanged();

    } else {
        set1 = new BarDataSet(entries, "Engine Types");

        ArrayList<Integer> colors = new ArrayList<Integer>();

        for (int c : ColorTemplate.VORDIPLOM_COLORS)
            colors.add(c);

        for (int c : ColorTemplate.JOYFUL_COLORS)
            colors.add(c);

        for (int c : ColorTemplate.COLORFUL_COLORS)
            colors.add(c);

        for (int c : ColorTemplate.LIBERTY_COLORS)
            colors.add(c);

        for (int c : ColorTemplate.PASTEL_COLORS)
            colors.add(c);

        colors.add(ColorTemplate.getHoloBlue());

        set1.setColors(colors);


        ArrayList<IBarDataSet> dataSets = new ArrayList<IBarDataSet>();
        dataSets.add(set1);
        mChart.getXAxis().setValueFormatter(new IndexAxisValueFormatter(labels));
        //mChart.getXAxis().setValueFormatter(new LabelFormatter(labels));
        //mChart.getXAxis().setValueFormatter(new BarValueFormatter(set1));
        BarData data = new BarData(dataSets);
        data.setValueTextSize(50f);
        data.setValueTextColor(Color.WHITE);
        data.setValueTypeface(mTfLight);



        mChart.setData(data);


    }

}

在我的主要活动中，我像这样使用它：

 mChart.getXAxis().setValueFormatter(new IndexAxisValueFormatter(labels));

如果要将xAxis标签与每个条形图的中心对齐，请将setCenterAxisLabels属性设置为false

xAxis.setCenterAxisLabels(false);
