How can I rename blanks in a graph that displays values for related and not related records?

[LBRo]

Hello!

I have 2 tables related by ID. Table 1, has groups A, B, and C. Table 1 has IDs from 1 to 5, while Table 2 has IDs from 1 to 10. Not all Table 1 IDs are in Table 2. When I create a chart with values from Table 2 and the classification from Table 1, there's a bar that appears blank for the non-related IDs. How can I change the name on the X-axis to display A, B, C, and "Not in a group" 

I would like to create this chart without excluding the blanks but renaming them.

Same idea but using the data model and COALESCE

Hi @LBRo 

You can add a calculated column :

Group = LOOKUPVALUE(Groups[Group],[Id],[ID],"Others")

And use it on the graph

pbix is attached
