Line Chart generation

Which is the best line chart generation tool. i need to us开发者_StackOverflow社区e it in ma web page. I could also be able to save it to image format. It should be able to plot graph based on a timeline such data pertaining to a particular range of time. I got sucked up using Google Chart. Problem with scaling in that. Any things else???

i highly recommend highcharts has a great documentation and awesome demostrations.

I'd recommend flot, it is lightweight, purely javascript based, and very powerful and extensible.

We've had good results with http://www.jqplot.com/.
