Ruby on Rails

I'm playing around with FLOT with Ruby and I'm having a hard time
passing the code to javascript; I know my javascript isn't reading the
data correctly from Ruby. I need some syntax help.

Ruby Code:

o={};
o= {'label' => "A", 'data' => @example.collect{|x|
[Time.utc(x.date).to_i, x.num]}}
render :text => o.to_json


I have successfully rendered the output as such:

{"label":"A","data":[[1281225600,1.31],[1281225600,1.31],[1281225600,1.25]]}

The HTML outputs this data only.




My javascript is as follows:


var obj = jQuery.parseJSON(text);
var options = {
lines: { show: true },
points: { show: true },
xaxis: { mode: "time", timeformat: "%m/%d/%y", minTickSize: [1,
"day"]}};

var data = obj;
$.plot(placeholder,[data],options);
}


I think the jQuery.parseJSON(text); isn't working. Any suggestions will
be helpful.
