For my application, i need to display the comparison parameters and statistics in graphs and charts. The input will be from JSP pages and at oracle is used as a repository. Drill down feature is also expected. This is one of the main features of my application so i am also looking for prettier graphs that used and configured easily. I came across few options: 1. JFreeChart, dont know it has drill down, but it is hard to use in web base environment. 2. How good and flexible, KavaChart is? I can spend reasonable amount on that but i just need to know that the solution is reliable and really meets my requirements.
I read about the yellow highlighted line under the graph is there even it is purchased, any ideas? Any idea about what alternative is better? KavaChart or ChartDirector?
Actually my company will pay for the stuff. I just want to be sure about the maturity of component and the conformity to my requirements, alos please can u give any comments on Jfreecharts or KavaCharts. I need to know which one is better.
yes, i have not tried Jfreecharts ,, but it has much more to offer, including many chart types and advanced features such as combined charts and chart mouse events ...
I've used JFreeChart, with CEWolf, and it works. It is fairly easy to do the example charts, but it can be quite complicated if you want to make any changes -- e.g., scale, tick marks, numbers, date ranges, etc. There is an active forum for JFreeChart, so sometimes you can get help with problems.
We had to read the source code for JFreeChart and CEWolf to get the charts we wanted (and they seemed like ordinary charts). We fixed at least one bug in CEWolf by extending a class.
There are many commercial charting packages. The one I hear the most about is Big Faceless Org's Java Graph Library: http://big.faceless.org/products/graph/
We haven't used it.
I can recommend _against_ QuadBase because it isn't meant to create graphics dynamically.
