问题描述

如何使用



我编辑了一个代码,我从github的一个示例项目中获得了代码。
如何将 100f和110f 值放在一个 Xaxis 标签整个数字

 得分1 =新得分(100f,0,Whole Number); 
mRealm.copyToRealm(score1);
分数score2 =新分数(110f,0,整数);
mRealm.copyToRealm(score2);


解决方案

是的, p>

你需要的是一个 BarChart 和多个 BarDataSets ,其中每个设置(在你的情况下)代表一种性别(男性或女性)。

示例代码(不包括realm.io)

 列表< String> xValues = ...; //丹麦,芬兰,... 

XAxis xAxis = chart.getXAxis();
xAxis.setValueFormatter(new MyValueFormatter(xValues));

//创建2个数据集
BarDataSet set1 = new BarDataSet(valuesMen,Men);
set1.setColor(Color.BLUE);
BarDataSet set2 = new BarDataSet(valuesWomen,Women);
set2.setColor(Color.RED);

BarData data = new BarData(set1,set2);
chart.setData(data);
chart.groupBars(...); //自发布v3.0.0以后可用
chart.invalidate(); //刷新

如果您需要进一步的帮助,请使用关于Wiki上提供的 BarChart



如果您想将 BarChart 中的值叠到彼此之上,您需要创建一个堆叠-barchart:


How can i compare two set of data using BarChart of MPAndroidChart.

It should look like this image below:

I edited a code, I get from a sample project in github.how can I put together 100f and 110f value in one Xaxis label Whole Number

        Score score1 = new Score(100f, 0, "Whole Number");
        mRealm.copyToRealm(score1);
        Score score2 = new Score(110f, 0, "Whole Number");
        mRealm.copyToRealm(score2);
解决方案

Yes, that can be done quite easily.

What you need is a BarChart with multiple BarDataSets where each set (in your case) represents one sex (men or women).

Example code (without realm.io)

    List<String> xValues = ...; // "Denmark", "Finland", ...

    XAxis xAxis = chart.getXAxis();
    xAxis.setValueFormatter(new MyValueFormatter(xValues));

    // create 2 datasets
    BarDataSet set1 = new BarDataSet(valuesMen, "Men");
    set1.setColor(Color.BLUE);
    BarDataSet set2 = new BarDataSet(valuesWomen, "Women");
    set2.setColor(Color.RED);

    BarData data = new BarData(set1, set2);
    chart.setData(data);
    chart.groupBars(...); // available since release v3.0.0
    chart.invalidate(); // refresh

If you need further assistance, here is a detailed tutorial on grouped BarChart available on the wiki.

If you want to "stack" values in a BarChart above each other, you need to create a stacked-barchart: Android Stacked Bars Chart
