Hey there,  
i have a partial set aside for a xml based pie chart, i dont want to do  
the  
array building inside the rhtml file though because afik, it would  
violate  
mvc. So, if i do a  
\<%= render :partial =\> “pie\_chart” %\>  
where do i put the data manipulation function, and variables that i want  
to  
be displayed in the  
\_pie\_chart.rhtml ?

thanks

This would be better answered on the rails mailing list. My guess  
would be that the data manipulation functions would be in the  
controller. That’s what it’s there for.
