The following code works fine as a independant page as itself. But if incorporated into my PHP web app, it throws error. How to debug if the error happens in the google chart JS? Any suggestions will be helpful

- I meant in my .ctp file. Sorry for the lack of clarity. I did figured it out that, due to inclusion of prototype-1.6.0.2.js, it is not working. :) – ravi.panch Commented Oct 14, 2011 at 16:00

Reset to default 9This answer will apply if you are using the Prototype JS framework. (I don't see it here, but it might have been excluded).
There is a ticket open for this issue on the Google Visualization API here.
One potential issue is that there might be a conflicting version of prototype or some other library being included.
Alternately, the reduce function may need to be redefined:
<script type="text/javascript">
Array.prototype.reduce = undefined;
</script>
[Note: I had this issue in the past, and this led to the solution. I am experiencing this issue a second time, but the original solution is not working for this new issue. Your mileage may vary.]
In my web app, I had included 'prototype-1.6.0.2.js', which created this error ! If I exclude 'prototype-1.6.0.2.js', everything runs great !
I had a similar issue where Google chart tools and Prototype library conflicted. I upgraded Prototype from version 1.6.1 to 1.7.1 and the problem was gone.
