Can I have values of a function field in graph?

I have a function field 'balance' for a Report named BalanceSheet and all other accounts which lie under it,and also for other type of reports.


The field 'balance' is not store(because we are doing a dynamic calculation, balance and total fields are not stored anywhere in the database)


So, is it possible to get the value of above mentioned field in Graph?

WHOA , I am sorry for above code, I didn't know it just pastes the text like this if I copy from my module, It's the 1st time you know as I'm a Beginner cum Learner of OpenERP as well as this form(Odoo). Can you just explain how can i display the 'balance' and 'total' fields in the Graph?

sure, functional field can be added just like any other field... and also it will be shown in measures.... you can refer Invoice Analysis... in that functional fields are used....

on 9/15/14, 10:01 AM

Okay I am going to refer Invoice Analysis, but maybe I've looked it up and in it, function fields are defined with property(parameter) STORE=TRUE, which means it is being stored somewhere in the database. In my case, we don't store 'balance' field, that's why it makes it to display in graph a TOUGH NUT TO CRACK. ANy more suggestions...!

Hmmmm... No idea which report you had check... Do check "account.invoice.report".. "user_currency_price_total" is a functional field which is not saved to db...

above said field is not used in Graph in the said module, so not useful for me though.
