JRobin 1.2.x releasedWhat's new?JRobin 1.2.0 stands to JRobin 1.1.0 like Windows 95 to Windows 3.11. Now you have an idea how big this upgrade was. Starting from release 1.2.0, JRobin ships as a standalone library (single jar-file without additional libraries). Arne Vandamme did a great job by rewriting the entire jrobin.graph.* package from the scratch. Finally, he removed the entire JFreeChart as a graphing tool and added many new options, improving the speed of the remaining code at the same time. Today, JRobin stands quite proudly side by side with RRDTool: you'll have a hard time trying to create a RRDTool graph which cannot be reproduced with JRobin. Check out our Gallery page to see some of the possibilities of JRobin. If you know how to use RRDTool, take a look at our quick reference page: switching from RRDTool to JRobin should be an easy task for any Java programmer! JRobin 1.2.0 has slightly different API compared to 1.1.0 version but many users won't notice this. We had also to change package names - JRobin has its own domain now and it was inevitable to reflect it in the source code. We apologize to developers who will have to recompile their code, but we promise huge benefits from that on the long run. Graphs produced with JRobin are now almost identical to those produced with RRDTool. Here are some sample graphs created with JRobin 1.2.0: Small historical note: When I started my work on JRobin, I was too lazy to write the entire jrobin.graph.* package from the beginning. Instead of it, I used JFreeChart library. In almost no time I got some decent graphs from RRD files. But I must admit that I was never happy with that solution: JFreeChart is, by Java standards, a huge library, much bigger than JRobin. I felt some discomfort while making my relatively small library dependent from a bigger one, just for graphing purposes. On the other hand, JFreeChart was not made with RRDTool graphing capabilities in mind: JFreeChart API is not sufficient (and probably will never be) to create the exact look&feel of RRDTool graphs. Well, JFreeChart is now obsolete and I hope that JRobin users who felt the same kind of discomfort are now satisfied. Other changes and improvements
