MPAndroidChart detail using --BarChart bar (a)

Today, to record what BarChart (bar chart) is simple to use!

Note: I use the version MPAndroidChart-v3.0.3 (Should have some way to update a different version, can leave a message in the comments area, do everything I can to help you solve!)
Details --LineChart line chart MPAndroidChart use of (a) ( simple to use)
in detail using the line graph MPAndroidChart --LineChart (b) (landscaping detail)

This article will talk about how simply draw bar (there is a little bit small landscaping)

First on renderings:

XML

<com.github.mikephil.charting.charts.BarChart
        android:id="@+id/bar"
        android:layout_width="match_parent"
        android:layout_height="300dp">
    </com.github.mikephil.charting.charts.BarChart>

Java

public class BarChartActivity extends AppCompatActivity {

    private BarChart bar;

    List<BarEntry>list=new ArrayList<>();//实例化一个List用来存储数据

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_bar_chart);
        bar = (BarChart) findViewById(R.id.bar);
        //添加数据
        list.add(new BarEntry(1,3));
        list.add(new BarEntry(2,8));
        list.add(new BarEntry(3,6));
        list.add(new BarEntry(4,9));

        BarDataSet barDataSet=new BarDataSet(list,"语文");
        BarData barData=new BarData(barDataSet);
        bar.setData(barData);

        bar.getDescription().setEnabled(false);//隐藏右下角英文
        bar.getXAxis().setPosition(XAxis.XAxisPosition.BOTTOM);//X轴的位置 默认为上面
        bar.getAxisRight().setEnabled(false);//隐藏右侧Y轴   默认是左右两侧都有Y轴
    }
}
