Showing direction arrows on hierarchical data
I have a set of data with a custom hierarchy (anonymised sample below
What I need to be able to do is display the data in a grid with a final column that shows the upward or downward movement at each level, with level 1 being the highest and being a sum of the levels below
| Level 1 | Level 2 | Level 3 | Level 4 | UFW_DEC | LastWeekUFW_DEC |
| Level 1_3 | Level 2_1 | Level 3_36 | Level 4_321 | 1747.74953 | 3589.94248 |
| Level 1_2 | Level 2_2 | Level 3_17 | Level 4_65 | 727.378 | 1106.822 |
| Level 1_2 | Level 2_2 | Level 3_27 | Level 4_122 | 529.94 | 529.94 |
| Level 1_2 | Level 2_2 | Level 3_35 | Level 4_137 | 1600.15219 | 3412.31348 |

I have a calculated column showing the difference between this week and last week and another one with this formula
↕ = SWITCH(
TRUE,
Main[Change]=0," ",
Main[Change]<0,UNICHAR(129095),
Main[Change]>0,UNIChar(129093))
which I found on another site.
The trouble is, it doesn't work, mainly I think because using a matrix, this new column is always forced to 'summarize' and with it being a string it defaults to 'first' (first of what though, and in what order). It tends to show only onw arrow (the down arrow) and sometimes shows blanks when clearly there isn't a change. Obviously doing something wrong but having trouble understanding the logic.

PS I tried this too
↕ = SWITCH(TRUE,Sum(Main[Change])=0," ",Sum(Main[Change])<0,UNICHAR(129095),Sum(Main[Change])>0,UNIChar(129093))PPS the CF I created to colour the arrows red or green seems to work fine so I'm thinking it's the 'first' summarization that's causing the problem
