alternative states in a line chart

[JOVI123]

Hey,

I'm looking for a solution for my problem.

I have this table:

Company name | Employes average wage | Companies economic sector | YearMonth

A                                    500$                                           Education                                      2017-June

B                                   12000$                                      Finance                                          2018-july

C                                   3654$                                         Education                                     2017-january

D                                  300$                                           Education                                      2017-june

A                                    500$                                           Education                                    2017-january

...

What I would like to do is to make a line chart where a company can see how she looks with a economic sector over time.

This is how it should look:

Green line is 75% quartile from the sectors wage,

Red line is 25% quartile from the sectors wage,

Blue is a companies wage median,

Yellow is sectors average wage

My problem is that when I choose a company sectors wage does not change as well as all quartiles. PLEASE HELP ME.

I wrote as so:

Green - Fractile({<[Companies economic sector]=B::[Companies economic sector]>}[Employes average wage],.75)

Red - Fractile({<[Companies economic sector]=B::[Companies economic sector]>}[Employes average wage],.25)

Yellow- Median({<[Companies economic sector]=B::[Companies economic sector]>}[Employes average wage])

Blue- if(Count (Distinct {B}[Company name])=1, AVG({B}[Employes average wage]))
