Top N by value

[nicoenz]

Hi everyone, 

I have a table with four columns (supplier, quantity, revenue, cost).

With this table i created a visual that uses a switch to show quantity/revenue/cost by supplier. 

Since the number of suppliers is huge i would like to filter the top 15 suppliers based on the field i selected in the switch (if i select quantity i would like to have the top 15 suppliers based on quantity)

Currently what i do is: In the "Supplier" filter in the "Filters on this visual" section i select TopN and then I need to put a "By value".

I can't make all this work.

Any suggestions?

thanks in advance!!!

this is what i have"

The visual: each column is a region, each colour is a supplier

The switcher with which i select to change the report in the visual (quantity or value). This selects which column to sum

This is the filter. When i put the measure switcher I get the "First of..." (which shouln'd be)

and if I apply the filter it doesn't do anything to the chart

Hi @nicoenz if you have a lot of rows, I suggest you to create separate table to get lower number of rows so this newly created table is source  for your visual.

In addition, TOPN is specific function "TOPN does not guarantee any sort order for the results." this could be the reason for your result and motivation to creat shorter table.

hi @some_bih ,

in the visual i only sum all the values. I don't use any topn expression. I was just summing all the values in the column and using the filter in the Filters pane

Hi @nicoenz create dedicated calculated table based on your TOPN expression. This way you will limit number of rows to evaluate for visuals.
