Hellocharts框架是android的第三方好用的图表库。
1、Gradle导入

compile 'com.github.lecho:hellocharts-android:v1.5.8'

2、因为我使用的是LineChartView,其他的类推
初始化工作

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_my_level);

        abilityChart = (LineChartView) findViewById(R.id.abilityChart);
        myRankChart = (LineChartView) findViewById(R.id.myRankChart);

        getAxisXLables();//获取X轴标注
        initTheatLineChart();
    }

getAxisLables

//x轴的显示
    private void getAxisXLables(){
        for (int i=0;i<date.length;i++){
            mAxisXValuesList.add(new AxisValue(i).setLabel(date[i]));
        }
    }

 //初始化abilityLineChart的设置
    private void initTheatLineChart() {

        getAxisPoints();//获取坐标点

        Line line = new Line(mTheatPointValuesList).setColor(Color.parseColor("#E9967A")).setCubic(true);//折线的颜色
        List<Line> lines = new ArrayList<>();
        line.setShape(ValueShape.CIRCLE);//折线图上每个数据点的形状
        line.setCubic(true);//曲线是否平滑
        line.setFilled(true);//是否填充曲线的面积
        //line.setHasLabels(true);//曲线的数据坐标是否加上备注
        line.setHasLabelsOnlyForSelected(true);//点击坐标显示数据
        line.setHasLines(true);//是否用直线显示
        line.setHasPoints(true);//是否显示原点
        lines.add(line);
        LineChartData data = new LineChartData();
        data.setLines(lines);

        //坐标轴
        Axis axisX = new Axis();//x轴
        axisX.setHasTiltedLabels(false);//X轴下面坐标轴字体是斜的显示还是直的显示，true是斜的显示
        axisX.setTextColor(Color.WHITE);
        axisX.setTextColor(Color.parseColor("#336699"));//灰色

        axisX.setName("能力曲线");//表格名称
        axisX.setTextSize(20);//设置字体的大小
        axisX.setMaxLabelChars(7);//最多几个X轴坐标，意思就是你的缩放让X轴上数据的个数7<=x<=mAxisValues.length
        axisX.setValues(mAxisXValuesList);//填充X轴的坐标名称
        data.setAxisXBottom(axisX);//X轴在底部

        Axis axisY = new Axis();//Y轴
        axisY.setName("");//Y轴标注
        axisY.setHasLines(true);
        axisY.setTextSize(11);
        axisY.setTextColor(Color.parseColor("#336699"));
        data.setAxisYLeft(axisY);//Y轴设置在左边

        abilityChart.setInteractive(true);
        abilityChart.setZoomType(ZoomType.HORIZONTAL);//缩放类型
        abilityChart.setMaxZoom((float)3);//缩放比例
        abilityChart.setLineChartData(data);
        //abilityChart.setVisibility(View.VISIBLE);

        Viewport v = new Viewport(abilityChart.getMaximumViewport());
        v.left = 0;
        v.right = 7;
        abilityChart.setCurrentViewport(v);
    }

//能力曲线的每个点的显示
    private void getAxisPoints() {
        for (int i=0;i<score.length;i++){
            mTheatPointValuesList.add(new PointValue(i,(float)theat[i]));
        }
    }

String[] date = {"5-23","5-24","5-25","5-26","5-27","5-28","5-29","5-30","5-31","6-1","6-2","6-3"};//X轴的标注
    double[] theat = {2.3,1.98,2.02,1.68,1.84,1.96,2.10,2.06,2.08,2.11,2.09,2.11};//能力曲线点数据
    private List<PointValue> mTheatPointValuesList = new ArrayList<>();
    private List<AxisValue> mAxisXValuesList = new ArrayList<>();
