[Lizmap] Dataviz problem

Hi Everyone,

I have a weird Dataviz problem: I am using a PostgreSQL view to extract 
data from a database with Date/Time as X-axis and different values on 
y-axis. So basically ID, sitenr, date, value fields. The Dataviz charts 
work perfectly, but: as soon as I add a join with other tables to add 
additional fields, the charts stop working.

Is it supposed to work like that? Are joins not allowed for the charts 
to keep working? Or what must I do to keep the charts working?


Linux server with PostgreSQL and QGIS 3.16 LTR, Lizmap 3.5 RC2, QGIS 
3.16 LTR desktop on Ubuntu 20.04
