I'm looking for an library, to generate charts on client side.
I found a lot, by searching on web and stackoverflow, like here
https://stackoverflow.com/questions/2227421/good-javascript-library-for-drawing-charts-using-json
or this very good collection:
http://sixrevisions.com/javascript/20-fresh-javascript-data-visualization-libraries/
There are so much alternatives, I'm a bit overwhelmed. Which one can use JSON data, which one is up to date, which one is easy to use (because I'm absolutely new on this topic), which one is robust, works on mobile phone (or not), which project is still alive, etc.
I need different chards, an line chart is mandatory. Also zoom in and zoom out is mandatory.
So I took a closer look on jqplot an flot.
Both providing zoom, but it looks like zooming is more an scaling. Which means: the granularity will not change by zoom in.
Because the graph will have a lot of data/points, i need to consolidate informations before sending them to the client. By zooming in, I need to rise the granularity, so the chart should be able to process new data for the zoomed area. (I hope I've made myself clear.)
Thanks for any kind of attention.
