Echarts

Echarts官网

Vue3.2+TS 示例

<div id="container2" style="height: 500px; width: 90%"></div>

const storageSize = ref<number>(0);
const storageRecords = ref<number>(0);

const qianzhi = reactive<any>({
  Type: Array,
  list: [],

const lineEcharts = () => {

        res = res.data.data

        qianzhi.list = res
        storageSize.value = res[(res as any).length - 1]['storageCapacity']
        storageRecords.value = res[(res as any).length - 1]['counter']

        let container: HTMLElement = document.getElementById("container1") as HTMLElement;
        let myChart = echarts.init(container);
        let app = {};

        let option;
        option = {
          tooltip: {
            trigger: 'axis',

JavaScript 按需引入

// 引入 echarts 核心模块，核心模块提供了 echarts 使用必须要的接口。
import * as echarts from 'echarts/core';
// 引入柱状图图表，图表后缀都为 Chart
import { BarChart } from 'echarts/charts';
// 引入提示框，标题，直角坐标系，数据集，内置数据转换器组件，组件后缀都为 Component
import {
  TitleComponent,
  TooltipComponent,
  GridComponent,
  DatasetComponent,
  TransformComponent
} from 'echarts/components';
// 标签自动布局，全局过渡动画等特性
import { LabelLayout, UniversalTransition } from 'echarts/features';
// 引入 Canvas 渲染器，注意引入 CanvasRenderer 或者 SVGRenderer 是必须的一步
import { CanvasRenderer } from 'echarts/renderers';

// 注册必须的组件
echarts.use([
  TitleComponent,
  TooltipComponent,
  GridComponent,
  DatasetComponent,
  TransformComponent,
  BarChart,
  LabelLayout,
  UniversalTransition,
  CanvasRenderer
]);

// 接下来的使用就跟之前一样，初始化图表，设置配置项
var myChart = echarts.init(document.getElementById('main'));
myChart.setOption({
  // ...
});

TypeScript 按需引入

import * as echarts from 'echarts/core';
import {
  BarChart,
  // 系列类型的定义后缀都为 SeriesOption
  BarSeriesOption,
  LineChart,
  LineSeriesOption
} from 'echarts/charts';
import {
  TitleComponent,
  // 组件类型的定义后缀都为 ComponentOption
  TitleComponentOption,
  TooltipComponent,
  TooltipComponentOption,
  GridComponent,
  GridComponentOption,
  // 数据集组件
  DatasetComponent,
  DatasetComponentOption,
  // 内置数据转换器组件 (filter, sort)
  TransformComponent
} from 'echarts/components';
import { LabelLayout, UniversalTransition } from 'echarts/features';
import { CanvasRenderer } from 'echarts/renderers';

// 通过 ComposeOption 来组合出一个只有必须组件和图表的 Option 类型
type ECOption = echarts.ComposeOption<
  | BarSeriesOption
  | LineSeriesOption
  | TitleComponentOption
  | TooltipComponentOption
  | GridComponentOption
  | DatasetComponentOption
>;

// 注册必须的组件
echarts.use([
  TitleComponent,
  TooltipComponent,
  GridComponent,
  DatasetComponent,
  TransformComponent,
  BarChart,
  LabelLayout,
  UniversalTransition,
  CanvasRenderer
]);

const option: ECOption = {
  // ...
};
