HTML in Pie Chart

Hi to all

I tried to add HTML in Tooltip Format string for a Pie Chart component and it works fine, but for some reasons it didn’t work with the Label Format string :scratch:

Here is my expresion for the Tooltip Format
concat(’

{1} Alarmes(s) sur {3}

{2}

')

Do you have idea ?
