resize method
Resizes the dygraph. If no parameters are specified, resizes to fill the containing div (which has presumably changed size since the dygraph was instantiated. If the width/height are specified, the div will be resized.
This is far more efficient than destroying and re-instantiating a Dygraph, since it doesn't have to reparse the underlying data.
Implementation
external void resize([num? width, num? height]);
