一键换肤（Echarts 自定义主题）

一、使用官方主题配置工具

官方主题配置工具：https://echarts.apache.org/zh/theme-builder.html

如果以上主题不满足使用，可以自己自定义主题

例如：修改背景、标题等，可按照设计师需求来更改

配置好之后，下载主题


有两种方式可选：JS 版本、JSON 版本，以 JSON 版本为例：
复制到项目中（ theme.json ），
theme.json 文件示例：

{"categoryAxis": {"axisLine": {"show": true,"lineStyle": {"color": "green"}},"axisTick": {"show": true,"lineStyle": {"color": "green"}},"axisLabel": {"show": true,"color": "green"} },"valueAxis": {"axisLine": {"show": false,"lineStyle": {"color": "green"}},"axisLabel": {"show": true,"color": "green"}},"legend": {"textStyle": {"color": "green"}}
}

注册主题：

// 引入主题
import theme from './theme.json'// 使用echarts
import echarts from 'echarts'
echarts.registerTheme('customTheme', theme)

使用：

//使用echarts
<div id="test">...
</div>
<script>let myChart = echarts.init(document.getElementById("test"),"customTheme");let option = {...}myChart.setOption(option);
</script>

完整代码：

<template><div id="main" style="width: 600px; height: 400px"></div>
</template><script>
import theme from "./theme.json";
import * as echarts from "echarts";export default {mounted() {//注册主题echarts.registerTheme("customTheme", theme);//初始化使用主题var myChart = echarts.init(document.getElementById("main"), "customTheme"); // 使用dark 、light或无第二参数myChart.setOption({xAxis: {type: "category",data: ["Mon", "Tue", "Wed", "Thu", "Fri", "Sat", "Sun"],},yAxis: {type: "value",},series: [{data: [150, 230, 224, 218, 135, 147, 260],type: "line",},],});},
};
</script>

如果是多主题切换，则可以将各个主题的颜色整合在一个文件，分别注册

{"lightTheme": {"categoryAxis": {"axisLine": {"show": true,"lineStyle": {"color": "#cccccc"}},"axisTick": {"show": true,"lineStyle": {"color": "#cccccc"}},"axisLabel": {"show": true,"color": "#cccccc"}},"valueAxis": {"axisLine": {"show": false,"lineStyle": {"color": "#cccccc"}},"axisLabel": {"show": true,"color": "#cccccc"}},"legend": {"textStyle": {"color": "#cccccc"}}},"darkTheme": {"categoryAxis": {"axisLine": {"show": true,"lineStyle": {"color": "#ffffff"}},"axisTick": {"show": true,"lineStyle": {"color": "#ffffff"}},"axisLabel": {"show": true,"color": "#ffffff"}},"valueAxis": {"axisLine": {"show": false,"lineStyle": {"color": "#ffffff"}},"axisLabel": {"show": true,"color": "#ffffff"}},"legend": {"textStyle": {"color": "#ffffff"}}}
}

这样的话，就可以对应官方示例中的这种（深色/浅色模式）
https://echarts.apache.org/examples/zh/editor.html?c=line-simple

二、上述不满足使用的情况

这是因为执行先后顺序

先使用主题色（初始化），再配置的 option，option 里的颜色覆盖了主题里的颜色。

这种情况下，我这边是用了笨办法，一个个去设置（大家如果有好的办法，可以交流下）

给 x 轴、y轴、图例、标题单独设置了 深色模式下的颜色。

定义 darkTheme.json 文件：

{"title": {"textStyle": {"color": "rgba(255,255,255,0.6)"},"subtextStyle": {"color": "rgba(255,255,255,0.6)"}},"tooltip": {"backgroundColor": "rgba(5,22,38,0.9)","borderColor": "rgba(5,22,38,0.9)","textStyle": {"color": "rgba(255,255,255,0.6)"}},"categoryAxis": {"axisLine": {"lineStyle": {"color": "#CCCCCC"}}, "axisTick": {"lineStyle": {"color": "#CCCCCC"}},"axisLabel": {"color": "rgba(255,255,255,0.6)"}},"valueAxis": {"axisLine": {"lineStyle": {"color": "#CCCCCC"}},"axisLabel": {"color": "rgba(255,255,255,0.6)"},"nameTextStyle": {"color": "rgba(255,255,255,0.6)"},"splitLine": {"lineStyle": {"color": "rgba(5,22,38,0.7)"}}},"legend": {"textStyle": {"color": "rgba(255,255,255,0.8)"}}
}

使用

<script>
import { cloneDeep } from "lodash-es";
import darkTheme from "./darkTheme.json";export default {props: {option: {type: Object,default: null,},},name: "ChartCustomEcharts",data() {return {baseChart: null,};},methods: {setOption(option = this.option) {if (option && this.baseChart) {const result = this.getThemeColors(option);this.baseChart.setOption(result, true);}},initChart() {this.baseChart = echarts.init(this.$refs["baseChart"]);this.setOption();},getThemeColors(data) {const option = cloneDeep(data)const themeType = this.themeType;if (themeType === "dark") {// 标题if (option.title) {if (option.title.subtextStyle) {option.title.subtextStyle.color = darkTheme.title.subtextStyle.color;}}// 图例if (option.legend) {if (option.legend.textStyle) {option.legend.textStyle.color = darkTheme.legend.textStyle.color;} else {option.legend.textStyle = darkTheme.legend.textStyle;}}// x轴if (option.xAxis) {if (Array.isArray(option.xAxis)) {option.xAxis.forEach((work) => {if (work.axisLabel) {work.axisLabel.color = darkTheme.categoryAxis.axisLabel.color;}if (work.axisLine) {if (work.axisLine.lineStyle) {work.axisLine.lineStyle.color = darkTheme.categoryAxis.axisLine.lineStyle.color;} else {work.axisLine.lineStyle = darkTheme.categoryAxis.axisLine.lineStyle;}}});}}// Y轴if (option.yAxis) {if (Array.isArray(option.yAxis)) {option.yAxis.forEach((work) => {if (work.axisLabel) {work.axisLabel.color = darkTheme.valueAxis.axisLabel.color;}if (work.axisLine) {if (work.axisLine.lineStyle) {work.axisLine.lineStyle.color = darkTheme.valueAxis.axisLine.lineStyle.color;} else {work.axisLine.lineStyle = darkTheme.valueAxis.axisLine.lineStyle;}}if(work.splitLine){if(work.splitLine.lineStyle){work.splitLine.lineStyle.color = darkTheme.valueAxis.splitLine.lineStyle.color;}else{work.splitLine.lineStyle = darkTheme.valueAxis.splitLine.lineStyle}}if (work.nameTextStyle) {work.nameTextStyle.color = darkTheme.valueAxis.nameTextStyle.color;}});}}// tooltipif (option.tooltip) {option.tooltip.backgroundColor = darkTheme.tooltip.backgroundColor;option.tooltip.borderColor = darkTheme.tooltip.borderColor;if (option.tooltip.textStyle) {option.tooltip.textStyle.color = darkTheme.tooltip.textStyle.color;} else {option.tooltip.textStyle = darkTheme.tooltip.textStyle;}}}return option;},},
};
