这就是我所取得的成就

CURRENT_CHART.png

绘制的代码如下

private void drawChart(){
    int[] x = { 1,2,3,4,5,6,7,8 };
    int[] happyness = { 5,2,4,1,0,4,5,0};
    int[] energy = { 5,4,3,1,4,3,5,0};
    int[] strenth = { 2,0,1,3,2,4,3,0};
    int[] endurance = { 0,2,1,4,3,5,2,0};

    // Creating an  XYSeries for Income
    XYSeries happynessSeries = new XYSeries("Happyness");
    // Creating an  XYSeries for Income
    XYSeries energySeries = new XYSeries("Energy");
    // Adding data to Income and Expense Series
    XYSeries strenthSeries = new XYSeries("Strenth");
    XYSeries enduranceSeries = new XYSeries("Endurance");

    for(int i=0;i<x.length;i++){
        happynessSeries.add(x[i], happyness[i]);
        energySeries.add(x[i],energy[i]);
        strenthSeries.add(x[i],strenth[i]); …
