Returns the number of dimension columns that have non-aggregation content. i.e. do not contain partial sums or collapsed aggregates.
A typical use is in attribute expressions, when you want to apply different cell formatting depending on aggregation level of data.
This function is only available in charts. For all chart types except pivot table it will return the number of dimensions in all rows except the total, which will be 0.
What does it mean?
We have Table with 4 dimensions(columns): Product,Category,Type,Sales
Now we want to create Pivot Table by using those Dimensions.
We are going to use only 3 of them(Product,Category,Type) and use 4th(Sales) in our expression.
The result is shown below:
This Pivot Table has 3 dimensions so its maximum dimensionality is 3.
For better understating please see table below.
The function is used to show on which dimensionality level each of the Pivot Table row is:
'Sugar' has dimensionality of 1 which is Total for that 'Product'.
'Salt' has dimensionality of 2 which is Total for each 'Category' of that 'Product'.
'Oil' has dimensionality of 3 which is single value for each 'Type' of the 'Product's' 'Category'.
So then more Dimension we use the greater dimensionality of our Pivot Table is.
1) To show the level of dimensionality:
if(Dimensionality()=1 ,RGB(151,255,255),if(Dimensionality()=2 ,RGB(0,238,0),if(Dimensionality()=3,RGB(255,130,171))))
2) Highlight background of rows which on each level fall into certain condition:
if(Dimensionality()=1 and sum(Sales)<150,RGB(151,255,255),if(Dimensionality()=2 and sum(Sales)<=20,RGB(0,238,0),if(Dimensionality()=3 and Sum(Sales)<=20,RGB(255,130,171))))
Otherwise you will need to make changes the this path - [Dimensionality.xlsx]

Really thanks allot on your information given, it helps to improve the presentation layer appearance attractiveness.
Robert, I've just edited the categories list of this article, if you don't mind. Nothing common with Deployment or Management.
Simple but in-depth explanation. I learned a new Qlik thing today.
Very good explanation about Dimensionality function!!
Great explanation. However, I am trying to use Dimmensionality using a drill down dimmension... is it possible to use it with drill down or only plain dimmensions?
if we want get this sum in horizontal then how i get this
Thank you for sharing
