ECharts--給圖表新增陰影

近期要做圖表,我選擇了 ECharts 做視覺化圖表,圖表的樣式有陰影。

js

//餅圖
app.title = '環形圖';

option = {
    tooltip: {
        trigger: 'item',
        formatter: "{a} <br/>{b}: {c} ({d}%)"
    },
    legend: {
        orient: 'vertical',
        x: 'right',
        data:['總量','使用']
    },
    backgroundColor:"#fff",
    color: ["#ececec","#fee529"],
    series: [
        {
            name:'訪問來源',
            type:'pie',
            radius: ['50%', '42%'],
            avoidLabelOverlap: false,
            itemStyle: { 
                normal: {
                    // 設定扇形的陰影
                    shadowBlur: 30,
                    shadowColor: 'rgba(255,227,42,0.3)', 
                    shadowOffsetX: -5,
                    shadowOffsetY: 5

                }
            },
            label: {
                normal: {
                    show: false,
                    position: 'center'
                },
                emphasis: {
                    show: true,
                    textStyle: {
                        fontSize: '16',
                        fontWeight: 'bold'
                    }
                }
            },
            labelLine: {
                normal: {
                    show: false
                }
            },
            data:[
                {value:500, name:'總量'},
                {value:200, name:'使用'}
            ]
        }

    ]
};

這塊程式碼主要是設定陰影的

itemStyle: { 
     normal: {
         // 設定扇形的陰影
         shadowBlur: 30,
         shadowColor: 'rgba(255,227,42,0.3)', 
         shadowOffsetX: -5,
         shadowOffsetY: 5

     }
 },

效果如下圖所示
