03 甜甜圈图

apexcharts数据可视化之甜甜圈图。

有完整配套的Python后端代码。

本教程主要会介绍如下图形绘制方式：

• 基本甜甜圈图
• 个性图案的甜甜圈图
• 渐变色的甜甜圈图

面包圈

import ApexChart from 'react-apexcharts';export function DonutUpdate() {// 数据序列const series = [44, 55, 13, 33]// 图表选项const options = {// 图表chart: {width: 380,type: 'donut',},dataLabels: {enabled: false},// 响应式responsive: [{breakpoint: 480,options: {chart: {width: 200},legend: {show: false}}}],// 图例legend: {position: 'right',offsetY: 0,height: 230,}}return (<div id="chart"><ApexChart options={options} series={series} type="donut" height={600}/></div>)
}

个性图案

import ApexChart from 'react-apexcharts';export function DonutWithPattern() {// 数据序列const series = [44, 55, 41, 17, 15]// 图表选项const options = {// 图表选项chart: {width: 380,type: 'donut',// 阴影dropShadow: {enabled: true,color: '#111',top: -1,left: 3,blur: 3,opacity: 0.2}},stroke: {width: 0,},// 绘图选项plotOptions: {pie: {donut: {labels: {show: true,total: {showAlways: true,show: true}}}}},labels: ["喜剧片", "动作片", "科幻片", "戏剧片", "恐怖片"],dataLabels: {dropShadow: {blur: 3,opacity: 0.8}},// 填充样式fill: {type: 'pattern',opacity: 1,pattern: {enabled: true,style: ['verticalLines', 'squares', 'horizontalLines', 'circles', 'slantedLines'],},},states: {hover: {filter: 'none'}},// 主题theme: {palette: 'palette2'},// 标题title: {text: "最喜欢的电影类型统计图"},// 响应式responsive: [{breakpoint: 480,options: {chart: {width: 200},legend: {position: 'bottom'}}}]}return (<div id="chart"><ApexChart options={options} series={series} type="donut" height={600}/></div>)
}

渐变

import ApexChart from 'react-apexcharts';export function DonutGradient() {// 数据序列const series = [44, 55, 41, 17, 15]// 图表选项const options = {chart: {width: 380,type: 'donut',},// 绘制选项：自定义开始角度和结束角度plotOptions: {pie: {startAngle: -90,endAngle: 270}},dataLabels: {enabled: false},labels: ["喜剧片", "动作片", "科幻片", "戏剧片", "恐怖片"],// 填充类型：渐变fill: {type: 'gradient',},legend: {formatter: function(val, opts) {return val + " - " + opts.w.globals.series[opts.seriesIndex]}},title: {text: '渐变甜甜圈与自定义的开始角度'},responsive: [{breakpoint: 480,options: {chart: {width: 200},legend: {position: 'bottom'}}}]}return (<div id="chart"><ApexChart options={options} series={series} type="donut" height={550}/></div>)
}
