vue3+ts+echarts饼图，封装的饼图组件，每次调用的时候颜色不重复？

方案1:随机生成颜色:

function getColor(){
                var color = "#";
                //一个十六进制的值的数组
                var array = ["0","1","2","3","4","5","6","7","8","9","a","b","c","d","e","f"];
                //得到6个随机数
                for (var i = 0; i < 6; i++) {
                    var num = parseInt(Math.random()*16);
                    color += array[num];
                }
                return color;
            }
