我有一个数据需要将其投影到图表上...我创建了一个表格，我在其中指定了整个周末，现在我只想在图表上投影工作日日期，不想在图表上看到周末。
| where name has "samplelog"
| extend Eventdate = strcat(datetime_part("day",timestamp))
| extend day_strg = tostring(Eventdate)
| extend day_num = dayofweek(timestamp) / 1d
| extend Week_Num = case(day_strg in (range(1, 7, 1)), "1", day_strg in (range(8, 14, 1)), "2",day_strg in (range(15, 21, 1)), "3",day_strg in (range(22, 31, 1)), "4", "0")
| extend weekend = iff(Week_Num in (2,4) and day_num == 6 or day_num == 0, "weekend", "working day")```
