echarts官网的动态数据 + 时间坐标轴实例的横坐标时间并不是当前时间,我对此进行了一些修改
vue项目
此图标的横纵坐标和title颜色都为白色
横坐标加上了倾斜效果

function randomData() {
        now = new Date(+now + 1000);
        value = value + Math.random() * 21 - 10;
        return {
          name: now.toString(),
          value: [now, Math.round(value)]
        };
      }
      var data = [];
      var now = new Date();
      var value = Math.random() * 1000;
      let myChart = echarts.init(document.getElementById("static"));
      let option = {
        title: {
            text: "动态数据 + 时间坐标轴",
            textStyle: {
              fontSize: 18,
              fontWeight: "bolder",
              color: "#fff" // 主标题文字颜色
            }
          },
        tooltip: {
          trigger: "axis",
          formatter: function(params) {
            params = params[0];
            var date = new Date(params.name);
            return (
              date.getDate() +
              "/" +
              (date.getMonth() + 1) +
              "/" +
              date.getFullYear() +
              " : " +
              params.value[1]
            );
          },
          axisPointer: {
            animation: false
          }
        },

            }
          },
          axisLabel:{
            interval:0,
            rotate:45,//倾斜度 -90 至 90 默认为0
          }
        },
        yAxis: {
          type: "value",
          boundaryGap: [0, "100%"],
          splitLine: {

          }
        },
        series: [
          {

            type: "line",
            showSymbol: false,
            hoverAnimation: false,
            data: data
          }
        ]
      };
      setInterval(function() {
        data.push(randomData());
        myChart.setOption(option);
      }, 1000);
