The JIDE Pivot Grid is a Java/Swing implementation of the famous PivotTable feature as you can find in Microsoft Office Excel as well as many other analytic and OLAP applications. A pivot table enables you to take what seems to be an indecipherable mass of facts and extract any trends and patterns buried in the data. You can organize and summarize your data, perform comparisons, and extract meaningful information that can be invaluable to you and your organization. It’s a very powerful tool and now you finally can use it in your Java application with several lines of code. JIDE Pivot Grid is built on top of the award winning JIDE Grids which provides a solid foundation for table related features in Java/Swing.
