 # chartjs-ror
 
 Simplifies using [Chart.js][] in Rails views.
 
 * All of Chart.js's features via one line of Ruby.
-* Renders charts on page load rather than DOMContentReady ([reason][browsersupport]).
 * Animates unless you have Modernizr and it doesn't detect canvas support ([reason][browsersupport]).  You can manually override this.
 * Optional alternative abscissa scale calculations (see [Chart.js#132][calculations]).
 * Optional utility method for filling in gaps in integer series.
