I want to filter out entries in my chart that don't fall between certain date range

[ehann2343]

I have a chart with entries that have a delivery date. I want to only show entries with a delivery date that falls between the first day of the current month (For example 10/1/2023) and the end of the next 3 months (For example 1/31/2024). 

Currently in my script I have these variables: 

let vTodayMonthStart = Date(MonthStart(Today()), 'MM/DD/YYYY');
let vTodayNext3mo = Date(MonthEnd(AddMonths(Today(), 3)), 'MM/DD/YYYY');

and my current attempt is an expression within the chart:
=Date([Delivery Date]) >= Date($(vTodayMonthStart)) and Date([Delivery Date]) <= Date($(vTodayNext3mo))

but it is not working. Anyone have a solution?

Make sure you have a calendar with MonthsAgo. This can be generated automatically with Autocalendar, or you can recycle that code and implement it in your calendar tables.

From there, you just need in your set analysis <MonthsAgo={0, '-1', '-2', '-3')}>

Realized I could just add the field that it was being filtered on as a dimension in the chart itself and hide the column.
