Hi,
Here is a table indicating the parent-child relationship within same table
[Refering the link(http://www.daxpatterns.com/parent-child-hierarchies/) I created Hierarchial Levels(Level 1 to Level 7)].
| Id | Title | State | ParentId | Level1 | Level2 | Level3 | Level4 | Level5 | Level6 | Level7 |
| 1 | Title1 | Resolved | 0 | 1 | ||||||
| 2 | Title2 | Completed | 1 | 1 | 2 | |||||
| 3 | Title3 | Proposed | 14 | 12 | 4 | 8 | 14 | 3 | ||
| 4 | Title4 | Committed | 12 | 12 | 4 | |||||
| 5 | Title5 | Started | 2 | 1 | 2 | 5 | ||||
| 6 | Title6 | Resolved | 10 | 12 | 4 | 8 | 14 | 3 | 10 | 6 |
| 7 | Title7 | Completed | 4 | 12 | 4 | 7 | ||||
| 8 | Title8 | Proposed | 4 | 12 | 4 | 8 | ||||
| 9 | Title9 | Committed | 2 | 1 | 2 | 9 | ||||
| 10 | Title10 | Resolved | 3 | 12 | 4 | 8 | 14 | 3 | 10 | |
| 11 | Title11 | Resolved | 3 | 12 | 4 | 8 | 14 | 3 | 11 | |
| 12 | Title12 | Completed | 0 | 12 | ||||||
| 13 | Title13 | Proposed | 2 | 1 | 2 | 13 | ||||
| 14 | Title14 | Committed | 8 | 12 | 4 | 8 | 14 | |||
| 15 | Title15 | Started | 8 | 12 | 4 | 8 | 15 |
Now,
I'm trying to present this data in a pie chart where "hierarchy"(i.e. Level1 to Level7) is legend & "count of 'Id'" as value.
Initially in the first level only 'Ids' 1 and 12 are shown. On drill down, by clicking 'Id' 1, I'm expecting the pie chart to show 'Id' 2 alone.
But, along with Id 2 , "Blank" is also shown.
Similarly when 12 is drilled down, Id 4 and Blank is shown. On further 4 is drilled down, 7, 8 & "Blank" is shown.
How to avoid Blank ?
