Question: I’d like to show the top items by a measure but allow my user to select the measure (e.g. swap between top 5 on Sales and top 5 on Profit). AND I want them to be able to change the number of top items (e.g. top 5 or top 10). How can I do this?
We’ve got some categories and are showing multiple measures for them. For example, below we’ve got Sales and Profit by Sub-Category and limited to our top 10 items on Sales:
But now, our user wants to look at this for the top 10 on Profit and then top 5 on Profit. How can we bake in this flexibility?
We’re going to build a few parameters to drive our sort and give us our top N. Parameters are great tools – your user can pick what they are interested in, and if you need to add something else to the list in the future, you can!
Our first parameter is for our sort options. For now, we’re making parameters with our core items: Sales and Profit:
We need a calculation that turns this into something we can reference. We’ll make a simple one that just calls up sum(sales) if Sales is selected, and sum(profit) if Profit is selected:
Finally, we’ll tell Tableau to sort by that calc, so right-click our dimension Sub-Category in Rows, and set to Sort by Descending:
Now, let’s make another parameter for Top n:
And set my filter to be based on Top n on Sort by, so my user can set the number they’re after:
PRESTO! Now, I can select my measure to Sort by and my Top n in my range. Hoorah!
