Hi all,
I'm almost sure that my json table generated by my script.php is right:
{"cols":[{"label":"idade","type":"number"},{"label":"quantidade","type":"number"}],"rows":[{"c":[{"v":"19"},{"v":1}]},{"c":[{"v":"20"},{"v":1}]},{"c":[{"v":"25"},{"v":1}]},{"c":[{"v":"37"},{"v":1}]},{"c":[{"v":"45"},{"v":2}]}]}
But anything appear when I tried to create the chart, by means of the code
below. Anybody knows the problem?
<html>
> <head>
> <!--Load the AJAX API-->
> <script src="http://code.jquery.com/jquery-latest.js";></script>
> <script type="text/javascript"

> </script>

I suppose it is not the problem, but I'm using wamp server... not using
databases, json and these stuffs, google charts works nicely with php in
wamp.
Thank you in advance.
