Override current dimension value in chart

Anonymous — Sat, 03 Nov 2018 17:10:23 GMT

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?

For example using

I was wondering if it was possible to solve this problem purely in the chart formula.

Apparently, not.

I'll proceed with this solution.

Thanks.

Actually, I found a solution without creating a new table thanks to the above post.

The winning formula is

sum(
  aggr(
    above(sum({1} Nights)),
    YearMonth
  )
)

"Calculate sum of nights for all the available dates, for each date get previous; intersect with the current chart context".

Brilliant.

Thanks.
