dynamic legend based on slicer selection - possible?

[po]

Hi,

Have a visual (map) and have slicer whereby  can view sales and put dimension in legend (e.g. customer or product)

Rather than duplicate the visual to say see sales qty by customer in legned and and sales qty by product in legend want to have a slicer whereby user can select either product or customer and legend wil change dynamically.

Can get the slicer part but believe legend needs to be a dimension.

How can this be best achieved?

Thanks

Hi @po ,

I have answered to a similar post a few days here is the data I used and the solution but adjusted to your needs

SALES:

PRODUCT_ID	VENDOR_ID	QUANTITY(€)	DATE
123	AAAAA	2	07/13/2020
221	BBBBB	5	07/13/2020

PRODUCTS:

PRODUCT_ID	CATEGORY	SUBCATEGORY
123	SPORTS	FOOTBALL
221	SLEEP	SHOES

VENDOR: 

VENDOR_ID	SHOP_TYPE	LOCATION
AAAAA	BIG	ITALY
BBBBB	SUPERMARKET	GERMANY

Create a table with both tables you need:

Type        Value

Product	Sports
Product	Sleep
Vendor	AAAAA
Vendor	BBBBB

Now do the following measure:

Sum Sales =
VAR SelectedType =
    SELECTEDVALUE ( Slicer[Type] )
VAR Selected_Value =
    VALUES ( Slicer[Value] )
RETURN
    SWITCH (
        SelectedType ;
        "Vendor"; CALCULATE ( SUM ( Sales[QUANTITY(€)  ] ); Vendors[VENDOR_ID  ] IN Selected_Value);
        CALCULATE ( SUM ( Sales[QUANTITY(€)  ] ); Products[CATEGORY  ] IN Selected_Value)
    )

Now use the measure as your values on the charts and the column of values on the legend as you can see legend is dinamic.

Hi,

Found and issue which seem to be encountering both on your example and one I'm working on.

If select slicer e.g. to show by vendor and then try apply filter on the vendor itself graph doesn't chnage to limit only to the filtered items. e.g.. in exmaple below woudl only expect value AAAAA.. to show 

Any thoughts on how we can get the graph to also show only the filtered values when select that in slicer and apply a filetr to the same item.

Hi @po ,

To filter out the column of the slicers for customer or product you need to select the columns from the slicer table and not from the vendor tables.

The slicer for products / vendors works in a disconnected way with the measure so the selection needs to be made on the disconnected table.

Add a slicer with the column Value from the Slicer table and you will understand how it works.

If you need any further assistance please tell me.

Hi,

Thanks for reply and explanation.

Also, looks like it works if add bit in bold say want to have slicer on vendor or filter on vendor 

SWITCH (

SelectedType ,

"Vendor", CALCULATE ( SUM ( Sales[QUANTITY(€) ] ), Vendors[VENDOR_ID ] IN Selected_Value, VALUES(Vendors[VENDOR_ID ])),

Thanks

Hi @po 

This also works but you are duplicating the vendors part in the measure since one vendor comes from the slicer table and other from the vendors table.

Hi, 

looks like if add VALUES(VENDOR_ID)  works o.k. not sure if this is best way to do it?

Thanks
