What is the correct token for trellis title category?

[mxh7777]

Hi,

I have a bar chart in trellis mode

The categories (LABEL 1 and LABEL 2) are obtained by aggregation

| timechart span=1h limit=0 c(eval(type_produit="LABEL 1")) as "LABEL 1" c(eval(type_produit="LABEL 2")) as "LABEL 2" by VALEUR

I have drilldown on this trellis and when I click on a part of the barchart, I want to catch the category of my selection (LABEL 1 or LABEL 2).

But I can't find the correct token to use.

I try these one :

$click.name$ => _time

$click.name2$ => name of VALEUR field

$click.value$ => 1658833200 (value of _time)

$click.value2$ => value of VALEUR field

$trellis.name$ => the token is not recognized (it stays $trellis.name$)

$trellis.value$ => the token is not recognized (it stays $trellis.value$)

Any idea ?

Thanks in advance
