raphael js setViewBox didn't resize my paper

问题

I have a problem with setViewBox on raphael, The paper isn't resized even if I did myPaper.setViewBox(0, 0, new_map_width, new_map_height,true); (Line 9 on the JS code)

Nb : new_map_width = 400 and new_map_height=300 and the map is at 800*600

this is my code : http://jsfiddle.net/xperali/zdbzJ/

I found the solution, I have to execute my setViewBox method after drawing all the paths, and use some math skills :)

var original_width = 777;
var original_height = 667;
var zoom_width = map_width/original_width;
var zoom_height = map_height/original_height;
if(zoom_width<=zoom_height)
   zoom = zoom_width;
else
   zoom = zoom_height;
rsr.setViewBox($("#"+map_name).offset().left, $("#"+map_name).offset().top, (map_width/zoom), (map_height/zoom));
