I have the following table which shows the sum of stock for each article, in that specific month.
I want to accomplish this:
ofcourse in the example the ?? values will be subtracted from december the previous year.
How can i accomplish this?
Perhaps you can achieve what you want with something like this:
If(Sum(Value)=0 or Len(Sum(Value))=0, Dual('??', 0), Num(Sum(Value), '#,##0'))
On the Presentation tab of the chart you should turn off the "Supress Zeros" option and on the Number tab you should make sure to select "Expression Default".

The problem is, in those months is no record, cause no mutations in the stock happened there.
Here is an example of a mutation:
For each values the mutations of that row are already subtracted
Is it as simple as just setting the "Null Symbol" and "Missing Symbol" in the presentation tab to "??"?
i tried "??" and ?? but it just shows the symbols in the table
It is difficult for me to answer your question without having access to your data and to the full requirements - and this is not the place to discuss those.
At this stage, I am not really sure what the query is that I am answering!
If a selection does not exclude a value, you should be able to make it appear in a chart. However, the problem can be that selections will exclude the value and so it will disappear.
Perhaps you could go back a step and explain what your data are, and what you are trying to display. Why do you need to display "??" at all?
If you are trying to display an exception report, I would think about how I could calculate the exceptions and display them in their own chart - otherwise they might get lost in a table of numbers.
With '??' i mean the value of the previous month.
The problem is that if there is no transaction in a certain month, the value of that month will be 0. So if I sum the totals of that month, the result is incorrect. Cause the 0 value is added
