Talk:LaTeX with Google chart

I think there is a maximum limit to the length of the mathematical expression, because the content is sent on the URL (HTTP GET). Maybe this should be mentioned, because I didn't realise about it and I got stuck for quite a while trying to understand what went wrong with my syntax. What do you think? --Gozzilli 16:01, 19 May 2010 (UTC)

Is there any possible way to extend the script for google api to automatically render plus signs into %2B? I simply added $code=str_replace("+","%2B",$code); but as i have no php experience it well may be it is very wrong.
