I got an urge to try out a data chart in my apps. After figuring the chart lib available in my ide is not that useful, I searched for the open source stuff. Downloaded jFreeChart and went thru the bundle. Didn't know where to start. Then I came to know that the user guide should be bought. Couldn't understand the open-sourceness of this project ..
... and then moved on to jChart. First thing I checked is the user guide and if they are charging for any of the free stuff. This is decent and easy to use. Compared to jFreeChart, jFreeChart has rich features and many more chart presentation. However, for a trial attempt, jChart is sufficient .. particularly if u r not going to make any extra bucks for putting a chart in the page.
