Hi,
Note that, if you work on QGIS 2.8, getFeature() and attribute() are
already part of core - no need to install a plugin.
However, there may be a quite negative impact on performance, if you
include such functions in your symbology impressions. So use them with
care, only if you really need them!

sorry... plugin installed...
I see all the functions in the field calculator but do you have a
small and quick example of what I am looking for?
I don't understand the function to use..
Thanks!

Hello,
You may give a look to /getFeature/ function (combining or not
with function like /attribute/ or spatial ones). There is also
/RefFunctions/ plugin that may help to use values/fields of
another layer.
But unfortunately, there is no list of such layers nor their
fields in the dialog. You need to write them yourself and their
values.

Hi all,
very simple question.
In the rule-based classification (vector) is it possible to
use values of another layer loaded in QGIS?
For example. Point vector and I want to display as red each
feature that has a value greater than a value stored in
another point layer (or in a table).
In the expression builder there are the fields of the active
layer.
Is it possible to call the fields of other layers?
Thanks
Cheers
Matteo
