They allow only 2k queries per month which is too little for me. Is there any classes or plugins or something I could use to create similar charts to Google's charts? Thanks.

1You have quite a bot of rep, so are not completely useless. What's wrong with [google](https://www.google.com/search?q=javascript+plotting+library)? – brice Mar 29 '12 at 15:13

this is also a perfect duplicate of [this question](http://stackoverflow.com/questions/119969/javascript-chart-library), which comes up on google search, no less. – brice Mar 29 '12 at 15:14

For anyone stumbling upon this question, there are no query limits [(<250k queries/day contact google)](http://googlecode.blogspot.com/2008/03/lifting-limit-on-calls-to-google-chart.html). See my answer below. – shaunsantacruz Mar 29 '12 at 16:14

There are tons of free alternatives!
http://teethgrinder.co.uk/open-flash-chart/ -- flash based http://www.highcharts.com/ -- javascript library! http://www.rgraph.net/ -- javascript library!
and a ton more
There are plenty, have a look around. Some I have used before include:
All of which are quite different, and all had their pros and cons. I'd say if you were to go for one of them my choice would be fusion charts (especially if you can fork out for the commercial version).

There are many Javascript graphing libraries but I'd recommend highcharts or flotr2.

Reading the docs the 2k limit you mentioned refers to the request URI data limit. You had me worried there as we're planning on using them soon. 2k queries per month would be a deal breaker for sure.
In 2008, they lifted any query limits. Feel free to use Google charts.
