Echarts本质

不管是哪种形式的图形，最本质的东西实际上是数据，它其实是对数据的一种可视化展示。使用Echarts，重点在于研究当前图表所需的数据格式。通常是需要后端提供符合格式要求的动态数据，然后响应给前端来展示图表。

具体返回数据一般由前端来决定，前端展示图表，具体折现图对应数据是什么格式，是有固定的要求的。 所以说，后端需要去适应前端，它需要什么格式的数据，我们就给它返回什么格式的数据。

营业额统计

根据接口设计VO，VO略。

// controller@GetMapping("/turnoverStatistics")@ApiOperation("营业额销售统计")public Result<TurnoverReportVO> turnoverStatistics(@DateTimeFormat(pattern = "yyyy-MM-dd") LocalDate begin,@DateTimeFormat(pattern = "yyyy-MM-dd") LocalDate end) {return Result.success(reportService.getTurnover(begin, end));}// service
