Histogram based on a filter

[vnqt]

Hi, 

 I would like to create a histogram as below : 

Here are the data

Name	Group	Sub-group
A1234	W123	AAA
B1234	w123	AAA
C1234	w456	AAA
D1234	w456	AAA
D1234	w789	AAA
D1234	w789	AAA
D1234	w456	AAA
E1236	w789	AAA
E1238	w456	AAA
A1236	w789	BBB
A1237	w123	BBB
D1237	w456	BBB
D1235	w456	BBB
E1237	w789	BBB
E1239	w456	BBB
B1236	w789	CCC
B1237	w123	CCC
E1234	w789	CCC
E1235	w123	CCC
A1235	w123	DDD
B1235	w456	EEE
C1235	w456	FFF
C1237	w123	III
C1236	w789	UUU

Could you please advise how I could exclude the Name where the Sub-group has only 1 Name: 

For example :  the following Name should be removed from the histogram

Name	Group	Sub-group
A1235	w123	DDD
B1235	w456	EEE
C1235	w456	FFF
C1237	w123	III
C1236	w789	UUU

Thank you in advance.

Hi,

You could create a new column like this: 

And then use that new column as a filter for the visual and exclude when value is less than 2. Or inlude only those that are greater than 1: 

I hope that helps 🙂

Thank you. 

Here is the DAX I use : 

= Calculate(DISTINCTCOUNT(Table[Name]), FILTER(Table, EARLIER(Table[Subgroup]) = Table[Subgroup]))

However, I find out that there are many "null" values in the column Sub-group. 

How could I compare the sub-group column which is in another table that has relation to this table?

I do something similar for the Matrix , then filter the value > 1. 

But for the histogram, I can't do this filter.

I am not sure what you are trying to do with the null values.

Would you want to use something like this? https://docs.microsoft.com/en-us/dax/lookupvalue-function-dax

Does the other table's sub group have null values as well?

Thank you for the info. I would try this.
