How to call the same interface in multiple places on the same page in a vue project?

I first thought of writing the interface into a method and then calling it somewhere else, but I didn"t know how to start
methods: {

/*  */
getData() {
  this.$http.get(this.$api.dataChart).then(rsp => {
    this.data = rsp.data.data; // tab
    console.log("555555", window.data);
  });
},
/*  */
createChartOne() {
  this.$http
    .get(this.$api.dataChart)
    .then(rsp => {
      console.log(rsp);

      if (rsp.status == 200) {
        window.data = this.data;
        this.resData = rsp.data.data.device_1;
        let key = "_1";
        let xAxisData = this.resData[key].names;
        let seriesData = this.resData[key].values; // 
        let yMin = Math.min.apply(null, seriesData);
        let yMax = Math.max.apply(null, seriesData);

        var home_echarts = echarts.init(
          document.getElementById("home_echarts")
        );
        var option = {
          grid: {
            left: 60
          },
          xAxis: {
            type: "category",
            data: xAxisData,
            axisLabel: {
              show: true,
              textStyle: {
                color: "-sharpfff"
              }
            },
            axisLine: {
              lineStyle: {
                color: "-sharp285555"

            }
          },

            type: "value",
            min: yMin - 5,
            max: yMax + 5,
            // splitNumber:5,
            // interval:parseInt((yMax- yMin)/5),
            axisLine: {
              show: true,
              lineStyle: {
                color: "-sharp275454"
              }
            },
            axisLabel: {
              show: true,
              textStyle: {

            }
          ]
        };
        var resize = {
          width: 415,
          height: 290
        };
        home_echarts.resize(resize);
        home_echarts.setOption(option);
      } else {
        throw rsp.message;
      }
    })
    .catch(err => {
      console.log("createChartOne", err);
    });
},

extract it like this

/*  */
getData() {
    return this.$http
            .get(this.$api.dataChart)
            .then(rsp => {
                if (rsp.status == 200) {
                    return rsp.data
                } else {
                    throw rsp.message;
                }
            })
            .catch(err => {
                console.log("createChartOne", err);
            });
},
createChart(el, data) {
    //echarts
},
createChartOne() {
    this.getChartData().then(data => {
        this.createChart("home_echarts", data);
    });
},
createChartTwo() {
    this.getChartData().then(data => {
        this.createChart("home_echarts_speed", data);
    });
}

mention a file and refer to it where needed
