The chart will have time for the x axis and a value for the y axis.
I'm needing to generate a line chart over time using a collection of data points.
Ideally the data points will appear as dots along the line that you can hover over and see the values of. But that will be in the enhanced phase, for now I just want to get a line chart to show up after feeding in some data points.
Does richfaces have a tag that i should look into for something like this? Or any other tips would be appreciated.
edit:
Im also needing my site to import a google map, and then be able to read my projects and from that generate points along the map with web channels going between the points. I know richfaces has the gmap tag but Im not sure if this is what i should be focusing on or not so any help with this will be appreciated too

One way of embedding charts in web apps is to use the cewolf tag library (which uses JFreeChart to create chart images). See the link in my signature for more information.

JSFlot is a JSF Chart library that is compatible with RichFaces. It can draw in-browser interactive charts using JavaScript. Most modern browsers are supported. JSFlot also has AJAX Functionality embedded so that the chart can be updated via drag-and-drop (Drag the chart to the right or left to move the timeline (X-Axis)).
JSFlot is Open Source and released via Google Code. JSFlot Google Code Site under the MIT license.
There is also a Live Demonstration of JSFlot here: JSFlot Live Demo
Some example charts generated with JSFlot:

Joachim,
Although this portion of the project is now being handled by another member of the team, I went ahead and sent this to him, because this is exactly what we were looking for.
Thanks for the reply and Im sure Ill be using this library in the future for my own projects.

Thank you Matt. Glad it fits your needs. I'm currently working on making JSFlot more interactive with overlays and the possibiity to click and select data points, chart zooming, etc. In the end it should make for a rather complete charting library.
