直接上效果图

使用前确保你安装引入了echarts，获取到了dom

 <div id="line1" style="height: 240px; width: 100%"></div>

折线配置

var chartDomline1: any = document.getElementById("line1");
var myChartline1: any = echarts.init(chartDomline1);
var optionline1;
 optionline1 = {
    grid: {
      left: "3%", // 图表距离容器左侧的距离
      right: "3%", // 图表距离容器右侧的距离
    },
    xAxis: {
      type: "category",
      data: [
        "2024-01-07",
        "2024-01-08",
        "2024-01-09",
        "2024-01-07",
        "2024-01-10",
        "2024-01-11",
        "2024-01-12",
      ],
    },
    yAxis: {
      type: "value",
      axisLabel: {
        formatter: "{value} 分", // 这里的'{value}'会被替换为实际的Y轴值，'单位'是你想要添加的单位
      },
      interval: 5, // 设置Y轴刻度间隔为5
      min: 0, // 设置Y轴最小值为0
      max: 25, // 设置Y轴最大值为100
    },
    series: [
      {
        data: [5, 6, 5, 18, 16, 21, 15],
        type: "line",
      },
    ],
  };

  option && myChartline1.setOption(optionline1);
