下面的代码是从 MongoDB 中获取数据，并在日期范围 (sum(prepayment_amount) and sum(total_prepayment_amount) group by checkin_from date) 内的图表中绘制金额和日期的总和。金额的总和位于 y 轴 中，日期位于 x 轴 中。
从这段代码中，我得到了金额和日期的总和，但问题是，
查看日期和时间2017-10-05T19:07:17Z & 2017-10-05T00:00:00Z。在这种情况下，(sum(prepayment_amount) 和 sum(total_prepayment_amount) 日期分别绘制。
如果日期和时间是 2017-10-05T00:07:17Z & 2017-10-05T00:00:00Z，我得到的结果是正确的。
我不知道问题出在哪里。我添加了预期的结果。任何帮助，将不胜感激。谢谢

请检查图像，在这里您可以找到问题。为了更好地理解，我还在 x 轴上列出了时间。
注意:图中数据与问题数据不匹配，因为我已将数据库与测试服务器连接。
最佳答案
在 $group 中，您将 $checkin_from 直接用作带时间的日期，因此它按日期和时间分组。
答案是使用 $dateFormat所以我们只有日期没有时间:
'_id' => ['checkin_from' => ['$dateFormat' => ['date' => '$checkin_from', format => '%Y-%m-%d']], 'cabinname' => '$cabinname']
关于php - Mongo groupby 在 Laravel raw 方法中没有使用不同的时间，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/45568957/
