Mini chart in QlikSense showing incorrect data

[Kaushik2020]

Hi All,

I am creating a Mini chart using Bar to show ticket raised trend for the past 6 months. 

This month the count is more than the Previous month. But if you see the mini chart, there is no such indication as part of bar chart representation. 

If I use Sparkline this tells me that the count of ticket is reduced. 

Diff column shows - Difference between MTD and LMTD.

Green color tells which month being highest.
Red color indicates which month being the lowest.

Expression to show trend: 

count({$<Year=, Month=, Day=,
DateKey={">=$(=Floor(Monthstart(Max(DateKey),-5)))"}>}
distinct Txt_IssueID)

For MTD:

count({$<Year=, Month=, Day=,
Date={">=$(=date(monthstart(max(Date))))<=$(=date(max(Date)))"}>}
distinct Txt_IssueID)

For LMTD: 

count({$<Year=, Month=, Day=,
Date={">=$(=date(monthstart(max(Date),-1)))<=$(=date(addmonths(max(Date),-1)))"}>}
distinct Txt_IssueID)

Please suggest.
