Creating a slicer that groups together values from a column

[Anonymous]

Hi,

I am trying to create a slicer that groups together various items in one column from an exisiting table.

For example, if my existing table contains a column "Food" like so:

Food

Strawberries

Carrots

Cucumbers

Cake

Banana

Orange

I would like to create a slicer with 3 options, Fruit, Vegetables and Dessert, where Fruit filters my dashboard to rows containing "Strawberries", "Banana" and "Orange, Vegetables filters to rows containing "Carrots" and "Cucumbers", and Desserts filters to rows containing "Cake".

Thanks

You could add a conditional column in Power query for a new column

OR

create a new table to use as the slicer using:

Slicer =
VAR Dessert =
    ADDCOLUMNS (
        CALCULATETABLE ( VALUES ( OriginalTable[Food] ), OriginalTable[Food] = "Cake" ),
        "Type", "Dessert"
    )
VAR Vegetables =
    ADDCOLUMNS (
        CALCULATETABLE (
            VALUES ( OriginalTable[Food] ),
            OriginalTable[Food] IN { "Cucumbers", "Carrots" }
        ),
        "Type", "Vegetables"
    )
VAR Fruit =
    ADDCOLUMNS (
        EXCEPT (
            VALUES ( OriginalTable[Food] ),
            UNION (
                CALCULATETABLE ( VALUES ( OriginalTable[Food] ), OriginalTable[Food] = "Cake" ),
                CALCULATETABLE (
                    VALUES ( OriginalTable[Food] ),
                    OriginalTable[Food] IN { "Cucumbers", "Carrots" }
                )
            )
        ),
        "Type", "Fruit"
    )
RETURN
    UNION ( Dessert, Vegetables, Fruit )

Or Create a copy of the table (Modeling -> New Table) and type Slicer = 'OriginalTable'
Then 

Then create a 1:* relationship between the food fields in both tables.

@Anonymous , Create  a new column and use that in the slicer

Switch( True() ,

[food] in {"Strawberries", "Banana" ,"Orange"} , "Fruit",

[food] in {"Strawberries", "Carrots" ,"Cucumbers"} , "Vegetables ",

"Desserts"

)
