Bar label contain 3 strings

[Amal BinHelal]

Hello
Dear Wenli,
I hope you find my email well

I want to have 3 string in the label but only i can have one with the value
{b} and {c}
 Let assume I have these data
{value:50, name: "user", description:"text", country: "France"}

How I can manage that ? to show it in bar label
Tried to have function with loop in formatter but it didn’t work

Thank you so much for your hard work I really precipitate your effort
