Good question, I was just looking for alternatives to JFreeChart myself the other day. JFreeChart is excellent and very comprehensive, I've used it on several projects. My recent problem was that it meant adding 1.6mb of libraries to a 50kb applet, so I was looking for something smaller.
The JFreeChart FAQ itself lists alternatives. Compared to JFreeChart, most of them are pretty basic, and some pretty ugly. The most promising seem to be the Java Chart Construction Kit and OpenChart2.
I also found EasyCharts, which is a commercial product but seemingly free to use in some circumstances.
In the end, I went back to the tried and trusted JFreeChart and used Proguard to butcher it into a more manageable size.
I suggest that you take another look at JFreeChart. The user guide is only available to buy, but the demo shows what is possible and it's pretty easy to work out how from the API documentation. Basically you start with the ChartFactory static methods and plug the resultant JFreeChart object into a ChartPanel to display it. If you get stuck, I'm sure you'll get some quick answers to your problems on StackOverflow.
There aren't a lot of them because they would be in competition with JFreeChart, and it's awesome. You can get documentation and examples by downloading the developer's guide. There are also tons of free online tutorials if you search for them.
There is JChart which is all open source. I'm not sure exactly what you are graphing and how you are graphing it (servlets, swing, etc) so I would say just look at a couple different ones and see which works for you.

I've also used JGraph but I've only used their commercial version. They do offer an open source version however:
EasyCharts is commercial so i couldn't use it for my project. I used the GRAL graphing library instead. I found it very easy to customize and it's licensed under LGPL just like JFreeChart, so you can use it for free:
I've used EasyCharts in the past and it lived up to it's name. It's not as powerful as JFreeChart, but the JAR for EasyCharts is much smaller than for JFreeChart.
I found this framework: jensoft sw2d, free for non commercial use (dual licensing)
regards.

For dynamic 2D charts, I have been using JChart2D. It's fast, simple, and being updated regularly. The author has been quick to respond to my one bug report and few feature requests. We, at our company, prefer it over JFreeChart because it was designed for dynamic use, unlike JFreeChart.
There is a new charting library in town: JChartlib JChartLib http://freshmeat.net/projects/jchartlib

You can try Jzy3d. It helps drawing simple 3d charts (surfaces, scatters, bars, etc), and has lot of options for customizing layout of axes, ticks, etc. There are lot of examples and a documentation on the wiki.
It's free and open source.
