Changing legend based on how I filter my line graph

[allora]

Hello! I have a line graph that shows sales and can be filtered by Country, State, and City. I have created one filter than can filter first by Country, then by State, and then by City.

My line graph has the following filters:

These are the filters being used on the slicer for my line graph:

The way it works now is, if i select a countries or multiple countries, I can see the sales for multiple countries at a time and it will show the results on different lines. This works as it should (see first image).

Now, let us say I click the drop down on Canada and select Quebec and Ontario, the graph combines the sales for the 2 states/provinces and shows them one line (see image 4). How can I get Quebec and Ontario on separate lines and have the legend reflect Quebec and Ontario instead of it showing Canada still?

Essentially, when I select just countries I would like the legend to show the countries, when I select states, I want to see the states, and when I select the cities I want the legend to show the cities.

The other thing that is happening is, lets say I select AZ from USA and Quebec from Canada. The graph will show me the results for these two states/provinces but the legend will continue to say USA and Canada instead of AZ and Quebec (see image 5).

Any tips would be appreciated!

Hey @allora ,

you can achieve what you are looking for by using the Field parameters feature: Let report readers use field parameters to change visuals (preview) - Power BI | Microsoft Learn

But at the current moment, it is a bit tricky to "simulate" the hierarchy. Maybe you can adapt the solution posted by @otravers here: Field Parameter - Hierarchy - Microsoft Power BI Community

Hopefully, this provides an idea of how to tackle your challenge.

Tom
