MPAndroidChart detail using --LineChart line graph (a)

Today, to record what LineChart (line 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!)

This article will talk about how to draw a simple line graph (there is a little bit small landscaping)

MPAndroidChart detail using --LineChart line graph (b) (depth landscaping)

First on renderings:

Since the code is relatively simple, so nothing can be particularly speaking, some comments in the code of

xml file

Just add such a control on it (is not very simple ~)

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

Java file

public class LineChartActivity extends AppCompatActivity {

    private LineChart line;

    List<Entry>list=new ArrayList<>();          //实例化一个 List  用来保存你的数据

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_line_chart);
        line = (LineChart) findViewById(R.id.line);
        
        list.add(new Entry(0,7));     //其中两个数字对应的分别是   X轴   Y轴
        list.add(new Entry(1,10));
        list.add(new Entry(2,12));
        list.add(new Entry(3,6));
        list.add(new Entry(4,3));
        
        //list是你这条线的数据  "语文" 是你对这条线的描述（也就是图例上的文字）
        LineDataSet lineDataSet=new LineDataSet(list,"语文");   
        LineData lineData=new LineData(lineDataSet);
        line.setData(lineData);

        //简单美化
        
        //   X轴所在位置   默认为上面
        line.getXAxis().setPosition(XAxis.XAxisPosition.BOTTOM);      
        //隐藏右边的Y轴
        line.getAxisRight().setEnabled(false);                        
    }
}

This way a simple line graph to draw good!
