render :partial => "filter_data", :locals => { :x1=>@x1, :y1 => @y1 }
then use x1 and y1 in the partial.  See
http://guides.rubyonrails.org/layouts_and_rendering.html#using-partials

If that still does not work then insert puts statements in the partial
to print the values of things to see what is going on.  The print will
appear in the server window.  Then you will know whether it is getting
the data to the view that is the problem or whether it is the view
code itself.
