Change line style (e.g. from constant to dotted) using cyclic group

[zfatima91]

I would like to turn the line on my line chart into a dotted line from a constant one just for the most recent period. Right now my dimension is a cyclic group called MonthWeekDay which includes fields for Month, Week ending and Dates.  

So far I have added expressions into text objects to break a part my expression but I am having a hard time pulling it all together when creating the expression under 'Line Style.'

This is what I have broken it down to so far:

=if(max(Month), '<S3>' , '<S1>') 

=GetCurrentField(MonthWeekDay)

Hi, can you try with?:

=if(max(Month)=max(TOTAL Month)-1, '<S3>' , '<S1>') 

If there are different years in your chart maybe you need a period field that identifies both (year and month), to get only the last one.

Hi Reuben,

Thank you for your help and sorry for the delay as I was on holiday! 

Your suggestion did work for the month dimension with GertCurrentField, however, for the weekend dimension I decided to use ReloadTime as that seemed like an easier option. I then used that for month as well. This is what I ended up with that worked: 

if(
(GetCurrentField(MonthWeekDay)= 'Week ending' and [Week ending] >= weekend(ReloadTime())-7)
OR
(GetCurrentField(MonthWeekDay)= 'Month' and monthstart(Month) = addmonths(monthstart(ReloadTime()),-1))
,'<S3>'
,'<S1>'
)
