【Echarts】使用多横坐标轴展示近十五天天气预报

现在手机都有天气app,使用echarts展示十五天天气预报的需要你遇到过这样离大谱的需求吗？如果没有或许你能从中找到些许思路。

效果

看效果是不是有点那么个意思,开局一张图,代码全靠ctrl + c。不多说上代码。

vue模板引擎代码

html 复制代码

<template>
  <div ref="xAxisChartRef" class="chart"></div>
</template>
<script setup lang="ts">
  import { onMounted, ref } from 'vue';
  import { useECharts } from '@/utils';
  import { options } from './options';

  let chart: EChartsType;
  const xAxisChartRef = ref();

  onMounted(() => {
    chart = useECharts(xAxisChartRef.value, options);
  });
</script>

<style lang="less" scoped>
  .chart {
    height: 300px;
    background: linear-gradient(90deg, #dde4ff, #fff, #fff, #dde4ff);
  }
</style>
