Show a message when there's no data

[Gems]

Is it possible to show a 'warning message' when there is no data for a variable instead of showing an empty section?

For example, in the bottom there's a big white space. Instead, I need a warning message like: 'For the variable chosen in the slicer, ther's no data'.

You can use the visual title's fx function, or you can use smart narratives to display the appropriate text.

Thank you @lbendlin , I've done some research and I find out that crating a Card and adding a measure on it was the easiest solution. Is imporant to adjust the transparency of the card to 100% in order to see the data when there are values to show. If this can help someone, this is the measure I used:

Measure = IF(ISBLANK(SUM('Variable')),"Message you want to display","")
