Visualising based on two level of calculation

[SadStatue]

Hi All,

I have fact table as below:

Person	Location	Date
A	a	1/01/2020
A	b	2/01/2020
A	c	2/02/2020
A	d	3/02/2020
D	a	1/01/2020
B	a	2/01/2020
B	b	2/02/2020
C	c	3/02/2020
C	d	4/02/2020

We have 4 person who works in different locations I need to calculate the number of locations they are working in dynamicaly (as I need to put a date slicer)

person	number of locations
A	4
B	2
C	2
D	1

But what I want to visualize as the final step is the frequency of the number of locations as below:

All in a dynamic manner so I can put a date Slicer

Thanks

@SadStatue , Not very clear. But see if binning and segmentation can help

@SadStatue - What is the x-axis in your graph represent? Is that the location (a b c d)?

[SadStatue]

It is the second column of the second table "Number of location". it shows that a person is took part in how many location.
I hope I could describe it!

@SadStatue - OK, I have mocked this up, seems to work. Requires a bi-directional relationship. Still not sure if it is what you are looking for. See attached PBIX file, you want Page 38, Table (38) and Table (38a).

@ me in your response.

@Greg_Deckler- Thanks for your work on this issue.

The second table (38a) is not a static table it is calculated from the fact table. so when I choose 1/1/2020 on the slicer there should be 2 person in 1 (in X axis) not 1 person in 1, and 1 in 4.
what I want is to calculate 38a[number of locations] based on the date range is selected in slicer. and visualize it in such a graph.

Cheers

@SadStatue - OK, starting to get to the heart of this issue now. You, my friend, will need a disconnected table. It's the only way that I know of to do what you want to do. In general, to use a measure in that way, you need to use the Disconnected Table Trick as this article demonstrates: https://community.powerbi.com/t5/Community-Blog/Solving-Attendance-with-the-Disconnected-Table-Trick...

Basically, you need a disconnected table to be your axis and then your measure forms the relationship between the disconnected tables. It's a bit of a mind bender to wrap your head around the first time but once you get it, it will be second nature...famous last words.
