注意点:版本号不一致会报错
1、echarts版本号为5.2.0
echarts-gl版本号为2.0.8
2、echarts版本号为 4.9.0,
echarts-gl版本号为 1.1.2,
这两种版本号都可以
二者都需要下载,使用npm下载
npm install echarts@5.2.0
npm install echarts-gl@2.0.8
import * as echarts from 'echarts';
import 'echarts-gl';

我的数据格式是对象里有,x,y,z,和颜色,你们自己的数据格式根据后端返回的格式来修改就可以

我个人的习惯是在methods里面写初始化图表的方法,在mounted钩子函数里面调用这个方法,你们也可以直接写在mounted函数里面
let chart = echarts.init(document.getElementById('main'));
let option = {
xAxis3D: {
type: 'value',
name: '',
axisLabel: {
show: true,
interval: 0, //使x轴都显示
},
},
yAxis3D: {
type: 'category',
name: '',
data: [11, 22, 33, 44, 55, 66, 77, 88, 99],
axisLabel: {
show: true,
interval: 0, //使y轴都显示
},
},
zAxis3D: {
type: 'value',
name: '',
},
tooltip: {
show: true,
formatter: function (params) {
let content = `
X: ${params.value[0]}<br>
Y: ${params.value[1]}<br>
Z: ${params.value[2]}
`;
return content;
},
},
grid3D: {
boxWidth: 300,
boxHeight: 140,
boxDepth: 200,
axisLine: {
show: true,
interval: 0,
lineStyle: {
color: '#2c3e50',
},
},
// 控制灵敏度,数值越大越灵敏
viewControl: {
distance: 400,
rotateSensitivity: 10, // 控制旋转的灵敏度
zoomSensitivity: 10, // 控制缩放的灵敏度
panSensitivity: 10, // 控制平移的灵敏度
},
},
};
因为所需要的格式是[x,y,z]这样的,所以需要更改我的数据格式
const convertedDataList = this.dataList.map((series) =>
series.map((point) => [point.x, point.y, point.z])
);
因为颜色值是固定的,每一条线是一个颜色,而不是一个点一个颜色,所以需要将颜色单独拿出来
let series = [];
// 设置颜色数组
//#region
const uniqueColorsSet = new Set();
this.dataList.forEach((series) => {
// 假设每个系列中的所有点都有相同的颜色,只取系列中第一个点的颜色
if (series.length > 0) {
uniqueColorsSet.add(series[0].color);
}
});
const uniqueColorsArray = Array.from(uniqueColorsSet);
设置name数组就是所需要设置legend时需要的
const uniqueName = new Set();
this.dataList.forEach((series) => {
// 假设每个系列中的所有点都有相同的颜色,只取系列中第一个的Y轴
if (series.length > 0) {
uniqueName.add(series[0].y);
}
});
const uniquNameArray = Array.from(uniqueName);
因为需要鼠标放上去有 tooltip提示,折现三维的话没有,只能使用点三维,所以一条数据中,需要同时设置一个点三维和线三维,循环数据获得
convertedDataList.forEach((item, index) => {
let series1 = {
type: 'scatter3D',
name: uniquNameArray[index],
symbolSize: 3,
itemStyle: {
color: uniqueColorsArray[index],
},
label: {
//当type为scatter3D时有label出现
show: true,
position: 'top', //标签的位置,也就是data中数据相对于线在哪个位置
distance: 0,
textStyle: {
color: '#2c3e50',
fontSize: 12,
borderWidth: 0,
borderColor: '#2c3e50',
backgroundColor: 'transparent',
},
},
data: item,
};
let series2 = {
type: 'line3D', //当type为line3D时有label没有作用,官网没有label这个配置项
name: uniquNameArray[index],
smooth: true,
lineStyle: {
width: 5, //线的宽度
color: uniqueColorsArray[index], //线的颜色
},
data: item, //线数据和点数据所需要的格式一样
};
series.push(series1, series2);
});
option.series = series;
option && chart.setOption(option);
window.addEventListener('resize', function () {
chart.resize();
});
mounted() {
this.drewLine();
},

因为我的数据中就添加了三个数据,所以有三条折现,如果想要有更多折现,可以在数据中继续添加数据
