apexcharts数据可视化之圆环柱状图
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：
- 基础圆环柱状图
- 多组数据圆环柱状图
- 图片背景
- 自定义角度
- 渐变
- 半个圆环图
- 虚线圆环图
基础圆环图
import ApexChart from 'react-apexcharts';
export function CircleChart() {
// 数据序列
const series = [70]
// 图表选项
const options = {
chart: {
height: 350,
type: 'radialBar',
},
plotOptions: {
radialBar: {
hollow: {
size: '70%',
}
},
},
labels: ['实时进度'],
}
return (
<div id="chart">
<ApexChart options={options} series={series} type="radialBar" height={550}/>
</div>
)
}
多值圆环图
import ApexChart from 'react-apexcharts';
export function MultiCircleChart() {
// 数据序列
const series = [44, 55, 67, 83]
// 图表选项
const options = {
chart: {
height: 350,
type: 'radialBar',
},
plotOptions: {
radialBar: {
dataLabels: {
name: {
fontSize: '22px',
},
value: {
fontSize: '16px',
},
total: {
show: true,
label: '合计',
formatter: function (w) {
// 默认情况下，此函数返回所有序列的平均值。
// 下面只是展示自定义格式化器函数使用的一个示例
return 249
}
}
}
}
},
labels: ['苹果', '橘子', '香蕉', '葡萄'],
}
return (
<div id="chart">
<ApexChart options={options} series={series} type="radialBar" height={550}/>
</div>
)
}

},
plotOptions: {
radialBar: {
// 雷达图图标
hollow: {
margin: 15,
size: '70%',
image: '/clock.png',
imageWidth: 64,
imageHeight: 64,
imageClipped: false
},
dataLabels: {
name: {
show: false, color: '#fff'
}, value: {
show: true, color: '#333', offsetY: 70, fontSize: '22px'
}
}
}
},
// 使用图片填充
fill: {

fontSize: '16px',
formatter: function (seriesName, opts) {
return seriesName + ": " + opts.w.globals.series[opts.seriesIndex]
},
},
}
},
