Is there a trace or troubleshooting plugin for Raphael?

I'm new to Raphael and exploring开发者_如何学编程 some of the animation features. I'd like to get trace info of, for example, animateAlong() at each stage of animation.

I've setup my own trace canvas object that I can put messages in which helps, but I'm sure someone must have created a trace plugin that's better than my attempt. I've searched but not found anything.

Much appreciate any help.

I've realised that I can manage with my own trace mechanism. Here's the Raphael:

var traceX = 5;
var traceY = 5;
var tracer = Raphael("trace");
function T(s) {
    traceY+=10;
    tracer.text(traceX,traceY,s).attr({
        'text-anchor': 'start'
    });
} // T()
T("TRACE");

// subsequent calls take the form:
T(s); // where s is the message

here's the HTML:
<div id="trace"></div>

and here's the css:
trace { background-color: #cdc; border: double 2px blue; height: 5000px; width: 300px; position: relativee; margin: 0; }
