I'm trying to build a table:
What I need is to show the actual previous month value (M-1) from the data model, not from the chart.
Using Above() is a bad idea because M-1 for "2018-Jan" shows null. My data range from 2012, so there is a value for 2017-Dec, but I can't get it.
How can I get the number of nights for 2017-Dec for the dimension 2018-Jan?

The As-Of Table
I was wondering if it was possible to solve this problem purely in the chart formula.
I'll proceed with this solution.
Actually, I found a solution without creating a new table thanks to the above post.
The winning formula is
"Calculate sum of nights for all the available dates, for each date get previous; intersect with the current chart context".
