前言

将接口返回的数据做一下简单处理，处理成组件要求的格式即可

一、处理前的代码

<template>
  <view class="charts-box">
    <qiun-data-charts 
      type="column"
      :opts="opts"
      :chartData="chartData"
    />
  </view>
</template>

<script>
export default {
  data() {
    return {
      chartData: {},
      //这里的 opts 是图表类型 type="column" 的全部配置参数，您可以将此配置复制到 config-ucharts.js 文件中下标为 ['column'] 的节点中来覆盖全局默认参数。实际应用过程中 opts 只需传入与全局默认参数中不一致的【某一个属性】即可实现同类型的图表显示不同的样式，达到页面简洁的需求。
      opts: {
        timing: "easeOut",
        duration: 1000,
        rotate: false,
        rotateLock: false,
        color: ["#1890FF","#91CB74","#FAC858","#EE6666","#73C0DE","#3CA272","#FC8452","#9A60B4","#ea7ccc"],
        padding: [15,15,0,5],
        fontSize: 13,
        fontColor: "#666666",
        dataLabel: true,
        dataPointShape: true,
        dataPointShapeType: "solid",
        touchMoveLimit: 60,
        enableScroll: false,
        enableMarkLine: false,
        legend: {
          show: true,
          position: "bottom",
          float: "center",
          padding: 5,
          margin: 5,
          backgroundColor: "rgba(0,0,0,0)",
          borderColor: "rgba(0,0,0,0)",
          borderWidth: 0,
          fontSize: 13,
          fontColor: "#666666",
          lineHeight: 11,
          hiddenColor: "#CECECE",
          itemGap: 10
        },
        xAxis: {
          disableGrid: true,
          disabled: false,
          axisLine: true,
          axisLineColor: "#CCCCCC",
          calibration: false,
          fontColor: "#666666",
          fontSize: 13,
          rotateLabel: false,
          rotateAngle: 45,
          itemCount: 5,
          boundaryGap: "center",
          splitNumber: 5,
          gridColor: "#CCCCCC",
          gridType: "solid",
          dashLength: 4,
          gridEval: 1,
          scrollShow: false,
          scrollAlign: "left",
          scrollColor: "#A6A6A6",
          scrollBackgroundColor: "#EFEBEF",
          format: ""
        },
        yAxis: {
          data: [
            {
              min: 0
            }
          ],
          disabled: false,
          disableGrid: false,
          splitNumber: 5,
          gridType: "solid",
          dashLength: 8,
          gridColor: "#CCCCCC",
          padding: 10,
          showTitle: false
        },
        extra: {
          column: {
            type: "group",
            width: 30,
            activeBgColor: "#000000",
            activeBgOpacity: 0.08,
            seriesGap: 2,
            categoryGap: 3,
            barBorderCircle: false,
            linearType: "none",
            linearOpacity: 1,
            colorStop: 0,
            meterBorder: 1,
            meterFillColor: "#FFFFFF"
          },
          tooltip: {
            showBox: true,
            showArrow: true,
            showCategory: false,
            borderWidth: 0,
            borderRadius: 0,
            borderColor: "#000000",
            borderOpacity: 0.7,
            bgColor: "#000000",
            bgOpacity: 0.7,
            gridType: "solid",
            dashLength: 4,
            gridColor: "#CCCCCC",
            fontColor: "#FFFFFF",
            splitLine: true,
            horizentalLine: false,
            xAxisLabel: false,
            yAxisLabel: false,
            labelBgColor: "#FFFFFF",
            labelBgOpacity: 0.7,
            labelFontColor: "#666666"
          },
          markLine: {
            type: "solid",
            dashLength: 4,
            data: []
          }
        }
      }
    };
  },
  onReady() {
    this.getServerData();
  },
  methods: {
    getServerData() {
      //模拟从服务器获取数据时的延时
      setTimeout(() => {
        //模拟服务器返回数据，如果数据格式和标准格式不同，需自行按下面的格式拼接
        let res = {
            categories: ["2016","2017","2018","2019","2020","2021"],
            series: [
              {
                name: "目标值",
                data: [35,36,31,33,13,34]
              },
              {
                name: "完成量",
                data: [18,27,21,24,6,28]
              }
            ]
          };
        this.chartData = JSON.parse(JSON.stringify(res));
      }, 500);
    },
  }
};
</script>

<style scoped>
  /* 请根据实际需求修改父元素尺寸，组件自动识别宽高 */
  .charts-box {
    width: 100%;
    height: 300px;
  }
</style>

二、处理后的代码

methods: {
			getServerData() {
				let tableData = {
					categories: [],
					series: [{
							name: "目标值",
							data: []
						},
						{
							name: "完成量",
							data: []
						}
					]
				};
				let param = {
					token: this.$storage.getStore("token")
				}
				let res = await getList(param)
				// 将获得的数据放进categories[],series.data[]中
				for (var i = 0; i < res.List.length; i++) {
					tableData.categories.push(res.List[i].data)
					tableData.series[0].data.push(parseInt(res.List[i].data)) //记得使用parseInt()转换数据格式为int格式
				}


				//模拟从服务器获取数据时的延时
				setTimeout(() => {
					//模拟服务器返回数据，如果数据格式和标准格式不同，需自行按下面的格式拼接

					this.chartData = JSON.parse(JSON.stringify(tableData));
				}, 500);
			},
		}

三、总结

思路就是把接口返回是数据通过数组的方法放到指定data中即可
