Hey Richard,

If there some facility to draw Quadrant chart using rGraph library ?

Almost. A look online tells me that a quadrant chart is a bubble chart with lines on it. No RGraph already makes bubble charts (using the Scatter):

www.rgraph.net/docs/howto-bubble-charts.html

After that it's just a case of drawing a couple of lines on it using the ondraw event.

obj.on('draw', function (obj)
{
     var ctx = obj.context;

     // Draw the cross hairs here
})
