效果图

只需要改动数值大小,自动根据大小排序。

在这里插入图片描述



上代码

    //右边横向条形图
    barGraph() {
      //初始化图标
      var myChart = this.$echarts.init(this.$refs["echart-right"]);
      //Y轴的数据,和数据值位置一一对应
      var cate = [
        "0001",
        "0002",
        "0003",
        "0004",
        "0005",
        "0006",
        "0007",
        "0008",
        "0009",
        "0010",
      ];
      //数据值,顺序和Y轴的名字一一对应
      var barData = [730, 801, 924, 1259, 1600, 411, 1090, 888, 466, 877];
      var option = {
        title: {
          text: this.rightname + "合格率排行榜top10",
        },
        tooltip: {
          trigger: "axis",
          axisPointer: {
            type: "shadow",
          },
        },
        //图表位置
        grid: {
          left: "3%",
          right: "4%",
          bottom: "3%",
          containLabel: true,
        },
        //X轴
        xAxis: {
          type: "value",
          axisLine: {
            show: false,
          },
          axisTick: {
            show: false,
          },
          //不显示X轴刻度线和数字
          splitLine: { show: false },
          axisLabel: { show: false },
        },
        yAxis: {
          type: "category",
          data: cate,
          //升序
          inverse: true,
          splitLine: { show: false },
          axisLine: {
            show: false,
          },
          axisTick: {
            show: false,
          },
          //key和图间距
          offset: 10,
          //动画部分
          animationDuration: 300,
          animationDurationUpdate: 300,
          //key文字大小
          nameTextStyle: {
            fontSize: 5,
          },
        },
        series: [
          {
            //柱状图自动排序,排序自动让Y轴名字跟着数据动
            realtimeSort: true,
            name: "数量",
            type: "bar",
            data: barData,
            barWidth: 14,
            barGap: 10,
            smooth: true,
            valueAnimation: true,
            //Y轴数字显示部分
            label: {
              normal: {
                show: true,
                position: "right",
                valueAnimation: true,
                offset: [5, -2],
                textStyle: {
                  color: "#333",
                  fontSize: 13,
                },
              },
            },
            itemStyle: {
              emphasis: {
                barBorderRadius: 7,
              },
              //颜色样式部分
              normal: {
                barBorderRadius: 7,
                color: new echarts.graphic.LinearGradient(0, 0, 1, 0, [
                  { offset: 0, color: "#3977E6" },
                  { offset: 1, color: "#37BBF8" },
                ]),
              },
            },
          },
        ],
        //动画部分
        
        animationDuration: 0,
        animationDurationUpdate: 3000,
        animationEasing: "linear",
        animationEasingUpdate: "linear",
      };
      myChart.setOption(option);
      //图表大小变动从新渲染,动态自适应
      window.addEventListener("resize", function () {
        myChart.resize();
      });
    },
