Question

使用水平mpandroid条形图可能是一个愚蠢的问题我在x轴上有数字像6,000,000所以x轴变得崩溃所以需要做的是将数字转换成印度卢比如6 cr我怎么能这样做到目前为止什么我试过的是：

这是设置水平条形图的值：

  ArrayList<BarEntry> entries = new ArrayList<>();
        ArrayList<String> labels = new ArrayList<String>();
        Format format = NumberFormat.getCurrencyInstance(new Locale("en", "in"));
      //  System.out.println(format.format(new BigDecimal("100000000")));



        for(int i=0;i<listobj.size();i++){
          String s=  format.format(listobj.get(i).getData());
        //    Log.e("ss", s);
//            Integer numberformat=Integer.parseInt(s);
            entries.add(new BarEntry(listobj.get(i).getData(),i));
            labels.add(listobj.get(i).getLabel());
        }
        XAxis axis=barChart.getXAxis();
        BarDataSet dataset = new BarDataSet(entries, "# of Calls");
        //dataset.setValueFormatter(new LargeValueFormatter());
        BarData datas = new BarData(labels, dataset);
      ///  datas.setValueFormatter(new LargeValueFormatter());
        barChart.setData(datas);
        barChart.setDescription("Description");
        barChart.getLegend().setWordWrapEnabled(true);

这是值Formatter：

        String r = mFormat.format(number);

        r = r.replaceAll("E[0-9]", SUFFIX[Character.getNumericValue(r.charAt(r.length() - 1)) / 3]);

        while (r.length() > MAX_LENGTH || r.matches("[0-9]+\\.[a-z]")) {
            r = r.substring(0, r.length() - 2) + r.substring(r.length() - 1);
        }

        return r;
    }

    }

我不知道如何自定义x轴值如何才能做到这一点任何人都可以帮助我提前感谢!!

Answer 1

您可以尝试两种方法来解决问题 1）插入值时，您可以将值除以1000,000并将标签更改为6Cr。我有一个图表，其值从0到30，一个值是4000.在将值存储在数据库中时，我将其除以100，并在显示时更改标签以显示正确的值示例SQL插入值：

 Float.valueOf(LEUCO_COUNT.getText().toString()) / 1000,

2）选项2是在显示之前将值除以1000,000，并修改你的babel以显示Cr。您可以通过API查找如何设置自定义标签

希望这有帮助。

Answer 2

您需要用以下功能替换现有功能。它适合我。

private String makePretty（double number）{

    double Cr = 10000000;
    double Lac = 100000;

    String result = mFormat.format(number);
    try {
        double LAmt = Double.parseDouble(result);
        String Append = "";
        if (LAmt > Cr) {//1Crore
            LAmt /= Cr;
            Append = "Cr";
        } else {
            LAmt /= Lac;
            Append = "L";
        }
        result = CommonUtils.GetFormattedString("" + LAmt) + Append;
    } catch (NumberFormatException e) {
        Log.d("", "");
    }
    return result;
}

如何在水平mpandroidchart中自定义x轴值？
