小程序中怎么使用echarts的流程在这边文章，点击去观看
我们项目需要实现一个带边框的雷达图，看了API之后没有发现怎么去实现这个边框，所以想到了画两个雷达图来实现这个边框，具体效果如上，代码如下文章来源：https://www.toymoban.com/news/detail-813127.html
// 初始化雷达图
init() {
let { optionsValue } = this.data;
function bar(canvas, width, height, dpr) {
const chart = echarts.init(canvas, null, {
width: width,
height: height,
devicePixelRatio: dpr,
});
canvas.setChart(chart);
let option = {
title: {
text: "自定义雷达图",
},
radar: [
{
indicator: [
{ text: "信任", max: 5 },
{ text: "冲突", max: 5 },
{ text: "承诺", max: 5 },
{ text: "责任", max: 5 },
{ text: "结果", max: 5 },
],
center: ["50%", "50%"],
radius: 110,
startAngle: 90,
splitNumber: 4,
shape: "circle",
name: {
formatter: "{value}",
textStyle: {
color: "#333333",
},
},
// 设置区域边框和区域的颜色
itemStyle: {
normal: {
color: "#FF92AC",
lineStyle: {
color: "#FF92AC",
},
},
},
splitArea: {
areaStyle: {
color: "#fff",
shadowColor: "rgba(0, 0, 0, 0.3)",
// shadowBlur: 10,
},
},
axisLine: {
lineStyle: {
color: "#E9E9E9",
type: "dashed",
},
},
splitLine: {
lineStyle: {
color: "#E9E9E9",
type: "dashed",
},
},
},
{
indicator: [
{
max: 100,
},
{
max: 100,
},
{
max: 100,
},
{
max: 100,
},
{
max: 100,
},
],
center: ["50%", "50%"],
radius: 111,
startAngle: 90,
splitNumber: 1,
shape: "circle",
splitArea: {
show: false,
},
axisLine: {
show: false,
},
splitLine: {
lineStyle: {
color: "#FF92AC",
type: "solid",
width: 2,
},
},
},
],
series: [
{
name: "雷达图",
type: "radar",
silent: false,
emphasis: {
lineStyle: {
width: 4,
},
},
symbolSize: 0,
data: [
{
value: optionsValue,
name: "图一",
symbol: "rect",
areaStyle: {
color: "#FF92AC",
},
itemStyle: {
normal: {
color: "#FF92AC",
lineStyle: {
color: "#FF92AC",
},
},
},
},
],
},
],
};
chart.setOption(option);
return chart;
}
let str = "ec.onInit.br";
let ec = { onInit: bar };
this.setData({
ec,
});
},
通过第二个雷达图跟第一个雷达图同心圆，半径比实际展示的大一点，splitNumber：1来实现一个只有外边框的雷达图文章来源地址https://www.toymoban.com/news/detail-813127.html
