问题描述

我正在使用MPAndroidChart显示包含两个数据集(收入和支出)的堆积条形图.当值为0时，标签与其他x轴值重叠时出现问题.

I am using MPAndroidChart to show a stacked bar chart containing two sets of data (Income and Expenditure). I'm having an issue when the value is 0 the label overlap other x axis values.

在屏幕快照的情况下，您可以看到具有值的条在以下日期具有重叠的值:14/4、15/4和16/4.

In the case of the screenshot you can see that the bars which have values have overlapping values for the following dates: 14/4, 15/4 and 16/4.

如何隐藏0值以停止重叠问题?> pp

How can I hide the 0 values to stop the overlapping issue?

推荐答案

使用IValueFormatter界面.

示例:

public class MyValueFormatter implements IValueFormatter {

    private DecimalFormat mFormat;

    public MyValueFormatter() {
        mFormat = new DecimalFormat("###,###,##0.00");
    }

    @Override
    public String getFormattedValue(float value, Entry entry, int dataSetIndex, ViewPortHandler viewPortHandler) {

        if(value > 0) {
            return mFormat.format(value);
        } else {
            return "";
        }
    }
}

将其设置为图表数据:

barData.setValueFormatter(new MyValueFormatter());
