echart-圖表位置改變

問題當legend比較長，圖表和legend裡的太近 可能會重疊擋住，效果不好

解決：

series: [
            {
                name:'人員級别',
                type:'pie',
                radius: ['35%', '70%'],
                center: ['60%', '50%'],// 圖表的位置 x,y方向
                avoidLabelOverlap: false,
                itemStyle: {
                    normal: {
                        //定義一個list，然後根據是以取得不同的值，這樣就實作了，
                        color: function(params) {
                            // build a color map as your need.
                            var colorList = [
                                '#ffd733','#feb18b','#2fd0fd','#51cd97','#9151cd','#feb18b','#2fd0fd','#51cd97','#9151cd'
                            ];
                            return colorList[params.dataIndex]
                        },
                        //以下為是否顯示，顯示位置和顯示格式的設定了
                        label: {
                            show: true,
                            position: 'right',
                            formatter: '{b}\n{c}'
                        }
                    }
                },
                label: {
                    normal: {
                        //show: false,
                        //position: 'center'
                    },
                    emphasis: {

                            }
                        },
