How to make some fields always shown, indipendently from the filters?

[MattiaIngAir]

Hi to everyone!
I'd like to show in the visual named "line charts" a line made by some data that's always shown and fixed and then other lines that depends on filters (i.e. slicers). For example, I want to compare the price chart of a financial index on y axis, on the x axis the date but I also want to show the options available on that index, that has to change accordingly with some slicers. So I want the chart of the index fixed on the visual e the price of the options being variable. The values of the prices (both for index and options) are in the same column and are split using the legend. I tried a lot of different solutions, but nothing worked. I am open to every solutions available, even modify the way the data are structured would be ok.

Hi @MattiaIngAir ,

 You can create a measure with the ALL function for a value that is independent of slicer selections.
