数据统计
Apache ECharts是一款基于JavaScript的数据可视化图表库,提供直观,生动,可交互,可个性定制的数据可视化图表。
入门案例
引入js文件(已提供)
为 ECharts 准备一个设置宽高的 DOM
初始化echarts实例
指定图表的配置项和数据
使用指定的配置项和数据显示图表
代码
<!DOCTYPE html>

营业额统计:
业务规则:
- 营业额指订单状态为已完成的订单金额合计
- 基于可视化报表的折线图展示营业额数据,X轴为日期,Y轴为营业额
- 根据时间选择区间,展示每天的营业额数据
接口设计:
前端需要什么格式的数据,后端去适应前端返回该格式的数据

在ReportServiceImpl实现类中创建私有方法getUserCount:

订单统计
业务规则:
- 有效订单指状态为 “已完成” 的订单
- 基于可视化报表的折线图展示订单数据,X轴为日期,Y轴为订单数量
- 根据时间选择区间,展示每天的订单总数和有效订单数
- 展示所选时间区间内的有效订单数、总订单数、订单完成率,订单完成率 = 有效订单数 / 总订单数 * 100%
