3、实现结果

(1)图形自分配颜色


(2)线条自定义颜色


(3)折点自定义颜色


4、问题说明

(1)设置折线线条颜色
        lineStyle:{
                 color:'#00FF00'
         }


(2)设置折线折点颜色

       itemStyle : {
                                normal : {
                                    color:'#00FF00'
                                }
                            }
