Questions about new x-axis constant line

[dapperscavenger]

Love the new x-axis constant line but can't figure this out.  Maybe it is not possible?

First question: can you have a constant line show every x period e.g 01 July of every year, or 01 of each month?

Second question: is it possible to use a dax measure instead of manually inputting the constant line, e.g set it to always be first day of previous month?  That way it automatically stays relevant without having to manually change it every month.

Hi @dapperscavenger , It is a very cool feature but I don't think it can do measures just yet! You can get the same functionality by changing a line chart to a combo chart, then adding this measure to the columns (keeping the others on the lines):

First Day Last Month =

var month = month(TODAY())-1

var year = if(month = 0, year(today())-1,year(today()))

var month2 = if(month=0,12,month)

var lastmonthdate = date(year,month,1)

return

if(SELECTEDVALUE('Date'[Date]) = lastmonthdate, 1, blank())
