根据以下要求编写代码：数据大屏项目主要技术包括Vue前端框架、Echarts图形库、Element-plus组件库以及后端数据接口开发（SpringBoot）、MySQL数据库等技术，但不仅限于以上技术。项目需要实现数据以图形的方式在Web页面端进行展示，以数据大屏项目方式设计，每个数据大屏不低于5幅图。

好的，根据您的要求，我可以为您提供一份参考代码，代码如下：

前端代码（Vue.js + Element-Plus + Echarts）：

<template>
  <div class="dashboard">
    <el-row>
      <el-col :span="12">
        <el-card>
          <div class="card-header">数据一</div>
          <el-divider></el-divider>
          <el-row>
            <el-col :span="16">
              <div class="chart-container">
                <div class="chart" ref="chart1"></div>
              </div>
            </el-col>
            <el-col :span="8">
              <div class="data-container">
                <div class="data-item">
                  <span class="data-label">数据1:</span>
                  <span class="data-value">{{ data1 }}</span>
                </div>
                <div class="data-item">
                  <span class="data-label">数据2:</span>
                  <span class="data-value">{{ data2 }}</span>
                </div>
              </div>
            </el-col>
          </el-row>
        </el-card>
      </el-col>
      <el-col :span="12">
        <el-card>
          <div class="card-header">数据二</div>
          <el-divider></el-divider>
          <div class="chart-container">
            <div class="chart" ref="chart2"></div>
          </div>
        </el-card>
      </el-col>
    </el-row>
  </div>
</template>

<script>
import * as echarts from 'echarts';
import { reactive, onMounted } from 'vue';
import { getChartData1, getChartData2 } from '@/api/dashboard';

export default {
  name: 'Dashboard',
  setup() {
    const state = reactive({
      data1: 0,
      data2: 0,
    });

    const initChart1 = () => {
      const chart = echarts.init(this.$refs.chart1);
      const option = {
        // echarts配置
      };
      chart.setOption(option);

      // 获取数据并更新图表
      getChartData1().then((res) => {
        state.data1 = res.data1;
        state.data2 = res.data2;
        chart.setOption({
          series: [
            {
              data: res.seriesData,
            },
          ],
        });
      });
    };

    const initChart2 = () => {
      const chart = echarts.init(this.$refs.chart2);
      const option = {
        // echarts配置
      };
      chart.setOption(option);

      // 获取数据并更新图表
      getChartData2().then((res) => {
        chart.setOption({
          series: [
            {
              data: res.seriesData,
            },
          ],
        });
      });
    };

    onMounted(() => {
      initChart1();
      initChart2();
    });

    return {
      state,
    };
  },
};
</script>

<style scoped>
.dashboard {
  padding: 20px;
}

.card-header {
  font-size: 18px;
  font-weight: bold;
  padding: 10px;
  background-color: #f5f5f5;
}

.chart-container {
  height: 400px;
  margin-bottom: 20px;
}

.chart {
  height: 100%;
}

.data-container {
  height: 400px;

  font-size: 18px;
  font-weight: bold;
  margin-right: 10px;

.data-value {

</style>

后端代码（Java + SpringBoot + MySQL）：

@RestController
@RequestMapping("/api/dashboard")
public class DashboardController {

  @Autowired
  private DashboardService dashboardService;

  @GetMapping("/chartData1")
  public Map<String, Object> getChartData1() {
    Map<String, Object> result = new HashMap<>();

    // 获取数据
    List<ChartData1> dataList = dashboardService.getChartData1();

    // 处理数据
    List<String> xData = new ArrayList<>();
    List<Integer> yData1 = new ArrayList<>();
    List<Integer> yData2 = new ArrayList<>();
    for (ChartData1 data : dataList) {
      xData.add(data.getDate());
      yData1.add(data.getData1());
      yData2.add(data.getData2());
    }

    // 构建返回结果
    result.put("seriesData", new Object[] { yData1, yData2 });
    result.put("xData", xData);

    return result;
  }

  @GetMapping("/chartData2")
  public Map<String, Object> getChartData2() {
    Map<String, Object> result = new HashMap<>();

    // 获取数据
    List<ChartData2> dataList = dashboardService.getChartData2();

    // 处理数据
    List<String> xData = new ArrayList<>();
    List<Integer> yData = new ArrayList<>();
    for (ChartData2 data : dataList) {
      xData.add(data.getDate());
      yData.add(data.getData());
    }

    // 构建返回结果
    result.put("seriesData", yData);
    result.put("xData", xData);

    return result;
  }
}

以上代码仅为参考，具体实现还需根据实际情况进行调整。
