I want to add text to a element in raphael js, I have added text with
r.text(30, 20, \"ellipse\").attr({fill: color});
But how to add this tex
Raphael does not have child/parent relationship between elements, so you will set same position for them e.g.
ec = paper.ellipse(190, 100, 30, 20);
paper.text(190, 100, "ellipse").attr({fill: '#ff0000'});
So if you want a ellipse with text, create your own JavaScript object which handles positioning of both.
or alternate way is to group elements via set
e.g.
var eltext = paper.set();
el = paper.ellipse(0, 0, 30, 20);
text = paper.text(0, 0, "ellipse").attr({fill: '#ff0000'})
eltext.push(el);
eltext.push(text);
eltext.translate(100,100)
