Is it possible to have some column calculations displayed in popups?

Given this example map:

https://atomotic.carto.com/builder/8238cb36-0f15-4fa4-9c80-cdce7c2bd040/embed

I would like to:

  • display a popup on a city that shows a value calculated using sum on a column,
  • access the value selected on category widget in order to compose an URL.
  • I don't really understand your second question. Please elaborate. – ramiroaznar Oct 10 '17 at 10:19
  • suppose i select the category Iuristarum from the Universitas widget: then i want to design a pop-up (using html editor) showing a link, for example my-site/universitas/iuristarum – raffaele messuti Oct 10 '17 at 16:55

First, add a Find centroid analysis to your layer. Grouping them by your city column and getting the sum aggregated value of your numero field. Then go to the POP-UP options and select category and value from the list of fields.
