Calculated dimension to only show a subset of a table

[#1]

Hi,

I want to add a table as a dimension for a graph, but I don't want the full table to be included in the graph, only a part of it.

I think this is a problem solved with calculated dimensions (correct me if I'm wrong), but I don't know the syntax for it.

I have a table Customers with customer ID 1, 2, 3, 4, 5. Instead of using the dimension "customerID" (which would result in 1-5) I only want to include the customer with the highest customer id. What is the syntax for this calculation? I'm guessing something like "=max(customerID)"?

If I only want to add the customers who have made over 10 orders, count(orderid)>=10, how do I add this restriction to my dimension?

hei attach is an example

hope its helps you

you can play with the variable give you more then one customer

At the Back end, you can create a flag with this condition and on the front end you can use If(condition = True,CustomerId) in the calculated dimension.

Hope it works ....

Thanks again RoiUser!

Is there a way to write the code so I don't need to use the variable maxCust?

Like:

aggr(if(Custid>=Max(Custid),Custid),Custid)

instead of:

aggr(if(Custid>=maxCust,Custid),Custid)

I tried just replacing the varible call "maxCust" with the acctual content of the variable "Max(Custid)" but it didn't work.

Also, is there a way to use Rank? So I can compare the values by relative size instead of acctual value? I figured Rank is better if the values aren't in perfect order (CustID 4, 6, 7, 9, 10, 13).

OK, i figured both things out for my self 😃

The code I should use is:

=aggr(if(rank(Custid)<=3,Custid),Custid)

Thank you RoiUser!

As a follow up question.

When I use my aggr rank function mentioned above on another dataset i get the result I want with the top 3, but it also includes an extra tuple which is a sum of the non-included tuples.The ghost tuple doesn't have a name, only a "-"

Example:

Adam 5, John 10, Dennis 8, Anna 12, Mat 6.

Top 3 would be Anna, John, Dennis. But as a result I get those three and then a fourth called "-" which has the value 11 (which is adam 5 + mat 6).

How do I get rid of the ghost value??

Edit:

FOUND IT! There's a tick box saying "don't show null values". Tada!
