Show only Current Month Data in Charts

[arpita]

Hi

I have data for multiple months and My script looks like below. I need to have all the month data in some charts and only latest month data few charts. How do I filter charts with only latest month data. (my latest month is previous month which as on date will be Nov 2020)

FXVOls:
LOAD
Status,
Product,
[Last Amend Date],
[Trading_Entity],
Date(Date#(mid(FileName(),46,2)&'/'&mid(FileName(),42,4),'MM/YYYY'),'MMM-YYYY') as Year _Month,
FROM
$(file)
(txt, codepage is 1252, embedded labels, delimiter is ',', msq);

I would create a variable on the front-end named vLatestMonth and set it to equal the following expression:
=maxstring(Year_Month)

Then in your expressions/measures for the charts you only want to show latest month, you would add logic to the set analysis like the following:
sum({<Year_Month={'$(vLatestMonth)'}>}Sales)
