Hi Dario,
Could you try with 'Colore' and not "Colore" (pay attention to the
simple vs double quotes)?

Hi, thank you for your reply, but I still don't understand how to
do... sorry
i tried to write this code in colour expression, but I don't
understand what "value" is in get_feature :
CASE
When
get_feature('V_TB_ATTIVITA_PT_NR',"Colore",'N')='N' then color_rgb (0,0,0)
When
get_feature('V_TB_ATTIVITA_PT_NR',"Colore",'R')='R' then color_rgb
(255,0,0)
END
Consider that I have a virtual field called "Colore" where I have 'N'
or 'R' in case it is black or red color.
Thank you for your kind availability.
cheers

You can select the layer under 'Plot Parameters' and its
attributes will be available in the expression. (see attached
screenshot).
If you need to get the attribute from another layer, you can use
the get_feature() function to get feature from another layer by
specifying the layer name.

Hi,
I should get some data from a specific field of a specific
layer but I’m stuck.
I’m using “Data Ploty” plug-in and I’d like to customise the
colour of the chart using expression.
As I’m working on layout I can’t see any field into expression
menu, so I need to call a specific layer and then the field.
I’d like to write something like that but, of course,
selecting the correct layer:
CASE
WHEN "Civici" = 'Neri' THEN color_rgb(0,0,0)
ELSE color_rgb (255,0,0)
END
Thank you in advance.
Cheers
