Dynamic Top N slicer (interaction with other Visuals)

[Anonymous]

Dears,

I have created a Top N slicer, which shows me the chosen Top N of Expenses of Assets. I have created a new Table, parameter and a measure "Top N Asset) for the slicer: see below the measure:

TOP N Asset =

VAR SelectedTop = SELECTEDVALUE('TOP N'[TOP N])

RETURN

SWITCH(TRUE();

SelectedTop = 0;[Expenses USD];

RANKX (

ALLSELECTED(Basis[Asset Name ]);

[Expenses USD]

)

<= SelectedTop;

[Expenses USD]

)

My Problem now is, that the Table with the Top N dont interagate with the other visuals. If I choose TOP 5 Assets, the table shows me the Top 5 but the other Visuals show me the all. How can I connect the new Table with my imported Table from Excel (called Basis).

I tried to make a relationship, but it doesnt work. I think because I dont have a column with the same values. I dont know how to copy the columns from the Table Basis to the new Table.

Maybe someone have an Idea, how I can solve that problem?

Thank you in advance.

Hi @Anonymous ,

If you want to copy some columns from one table, you can create a calculate table like this:

Copy table =
SUMMARIZE ( 'Table', 'Table'[column1], 'Table'[column2] )

Please refer: https://docs.microsoft.com/en-us/dax/summarize-function-dax 

If not help, could you please consider provide a dummy .pbix or sample data for further discussion?

Hi @v-yingjl 

below you can see a smal version of my Datatable (Basis).

Country	Category	Asset Name	Expenses USD	FEE	Activation	Media
Germany	Football	Accor Hotels Arena	2000	2000	0	0
Belgium	Venue	Olympia	3000	2000	1000	0
GB	Music	Zenith	4000	1000	2000	1000
Germany	Football	Football cup	5000	2500	2500	0
France	Venue	Federation Française de Football	6000	2000	2000	2000
France	Music	Paris Saint-Germain	7000	3000	2000	2000
France	Other	Paris Other	8000	2000	4000	2000

The other Table is parameter (What if): Generateseries(0;20;1) + the measure from my first post.

I want a slicer that shows me the Top N of Assets. I got it, but the slicer or the Table dont interact with the other visuals. The others show always all Assets, not the TOP N.

Is that enough?

Thank you, 

Albert

Hi @Anonymous ,

If you want to use the parameter to interact with other visuals, you can create a calculate column for rank first:

Rank = RANKX('Basis','Basis'[Expenses USD])

Then create a control measure, set its value as 1 and put it in the filter of the visual like table:

Slicer control = 
IF ( SELECTEDVALUE ( 'Basis'[Rank] ) <= [TOP N Value], 1, 0 )

The result may like this:

Here is the sample file that hopes to help you, please try it: PBIX 

By the way, which confused me is that if you want to show the topn result in the visual, why not create a rank column like the previous mentioned and use it as a slicer directly instead of using what-if parameters to create topN manually.

Hi @v-yingjl ,

Thank you for your help.

I tried the first approach, but it does not work correctly with my Data. When I choose 0, it shows me 3. Maybe the 3 Assets are wrong data. I dont know, why it shows me 3. If I choose 1, it shows me 4. So I think it something with the data.

The second approach is much more easier and makes more sense and it works. Thank you.

If you have a tip why the first approach may not work, it would be great. I am just interested, why.

Thank you 

Albert

Hi @v-yingjl, 

I have already tried that. The problem is, that then the Parameter doesnt work.

I also tried with "addclolumn" in the parameter it doesnt work to, maybe I did it wrong.
