Using Field Parameter in a Value field of matrix

[BrunoM]

Dear all, i am stucked in this situation, i need your help !
I have a simple data model.

A table "Indices" with a column date and 3 columns for Indice1, Indice2 and Indice3.
A table "_Dates" related to the first one.

I have create a slicerTable using Field parameter fonction.
I would like to use the slicer to choose the column i want to display. I am using 2 visuals (Matrix and Linechart).
When i assign them to the parameter field no value is displayed (Tab1 of the pbix file)

If if add directly the column in the visuals it is working :

I really do not understand why this is not working for columns.

In advance thank you for your help,

Hi @BrunoM 

To get this to work, create explicit measures for the average of each Indice:

Average of Indice1 =
AVERAGE ( Indices[Indice1] )

etc.

Then create a field parameter containing these three measures, and add this field parameter to the Values field well of the matrix.

The reason the original field parameter isn't working is that Indices[Indice1], Indices[Indice2], and Indices[Indice3] are treated as columns with no aggregation, so don't make sense in the Values field well of a matrix, and are therefore ignored.

When you drag the individual columns into the Values field well, it works because implicit measures are created (Average in your example).
