g.raphael.pie.label-center-align-fix.js

/* 
Have you ever used Graphael Pie chart (http://g.raphaeljs.com/) and found that when you use a really long legend label, it sometimes goes right off the screen and your chart doesn't align with it? This fixes that. 

It calculates the graph x to center align the labels with the chart.  This only works if you position the pie chart 'south' or 'north' in the 'legendpos' option.

var legend = ['Awesome', 'Legend', 'Labels whoa this is long'];
legend.sort(function(a, b){ return a.length < b.length; });
var longest_word = legend[0].length;
var x_offset = 1.5; // This might be different in your case. Mess around with it.

var graph_x = (graph_x / longest_word) * (longest_word / x_offset);
