I found this post - but it didn't work for me when filtering on Historical. Specifically, I created a beast mode as such:
CASE
WHEN Type
='Goal'then 'Historical'
When Type
='Renewal' and Actual_Date_Closed__c
<= LAST_DAY(DATE_SUB(CURRENT_DATE(), INTERVAL 1 MONTH)) and Type
='Renewal' THEN 'Historical'
ELSE 'Future'
END
I was hoping the results would remove this portion of the bar chart, which are future months of the year. I could get it to work on other bar charts, but not this line + bar chart, which makes me wonder if this is possible.
