Hi,

As of the next RGraph release (beta and stable) you will be able to chain Set() method calls. This means that you'll be able to do this:

var bar = new RGraph.Bar('cvs', [4,6,5,3,8,9])
     .Set('colors', ['red'])
     .Set('tooltips', ['Bob','Fred','Luis','Pete','Kevin','Rachel'])
     .Draw();

It won't mean any speed increase - but it may suit your coding style better.
