Openerp 7 Graph view i want to shows the output In X-axis Month Y-axis No of Count (Ex: Procedure Performed count)

The below Query is used:-

select  
               row_number() over () as id,
               pm.name as procedure_performed, 
               count(pm.name) as count_performed, 
               to_char(invoice.procedure_date, 'MM') as month
               from patientprocedure invoice
               inner join procedureperformed_rel performed on performed.intake_id = invoice.id 
               left join proceduretypemaster pm on pm.id = performed.proceduretype_id
               group by 
               pm.name,
               to_char(invoice.procedure_date, 'MM')

In the bar chart output shows Count of Procedure Performed values combined with the month and differentiate with colors.

Instead of how to shows the count of Procedure Performed separate based on month?.
