title: Create Excel Charts in Java
body: <p>I've been using Apache POI to create and modify Excel spreadsheets, but I'm wondering if there is a way (even if it's with a different library, preferably open source) to create charts in Excel in the new xlsx format. It looks like POI has an HSSFChart but I believe that's for the older format (please correct me if I'm wrong). Has anyone used a Java solution to create charts in Excel?</p>
