DAX Parameter Selected Value

Hi ,

My requirement is dynamically switch between different demographic categories using the slicer, display their proportions over time on the line chart, and add a reference line to show the gap for the selected category. I would like to see two lines one for young and one for muture with year on x axis, parameter on Legend and Proportion on Y axis.  I have created the table parameter for all the demographics categories lets say for example: 

Demographics =
DATATABLE(
    "Category", STRING,
    "Order", INTEGER,
    {
        {"Gender", 0},
        {"Age", 1},
        }   
YoungProportion =
CALCULATE(
    AVERAGE('table1'[proportion]),
    'table1'[Age] = "Young"
)
 
MatureProportion =
CALCULATE(
    AVERAGE('table1'[proportion]),
    'table1'[Age] = "Mature"
)
 AgeGap:YoungProportion-MatureProportion //This calculation is working OK for GAP calculation.
 
Here are is dax for selected category.
SelectedCategoryProportion =
VAR SelectedCategory = SELECTEDVALUE(Demographics[Category])
RETURN
    SWITCH(
        SelectedCategory,
        "Age",
            IF(
                HASONEVALUE('table1'[Age]),
                SWITCH(
                    VALUES('table1'[Age]),
                    "Young", [YoungProportion],
                    "Mature", [MatureProportion]
                )
            ),
        "Gender",
            IF(
                HASONEVALUE('table1'[Gender]),
                SWITCH(
                    VALUES('table1'[Gender]),
                    "Male", [MaleProportion],
                    "Female", [FemaleProportion]
                )
            ),
       
        BLANK()
    )                                                                                                                                                    If the age is selected , then it is showing blank for this selected category on the visuals . Could you please advise what is wrong in this above DAX calculation ? I am not getting any error message.
     
Many thanks for your help. Regards

Hi @Anonymous 

 

I have tested your problem and your code seems to be fine. The key to the problem lies in the creation of visual objects.

 

I suggest you create two visual objects that show the data corresponding to different parameters.

 

Select "Gender"

Select "Age"

Select "line chart", "Year" in the x axis, "SelectedCategoryProportion" into the y axis.

 

It should be noted that "Gender" and "Age" are placed into the "Small multiples" of the two visual objects respectively.

At the same time, you can adjust the visual object to two rows and one column.

Can you provide some sample data or pbix file? The cause cannot be determined because the model and context are not clear.
