Is it possible to access a custom property in the pen editor of an easy chart component ?  
It gives me an error  
If not is there a workaround to do that ?

[quote=“Fabrice CHAVEROT”]Is it possible to access a custom property in the pen editor of an easy chart component ?[/quote]No, the where clause must be a plain string.[quote=“Fabrice CHAVEROT”]If not is there a workaround to do that ?[/quote]Construct the “pens” data set with python, inserting the ID you need.
