--- Comment #14 from Roman Kashitsyn <[email protected]> 2011-07-17 20:41:44 UTC --- Created attachment 27294 --> https://issues.apache.org/bugzilla/attachment.cgi?id=27294 Draft of numeric cache implementation. Hi, I have finally finished first draft of number cache implementation. It not so easy as I thought. I have added some utils: 1. org.apache.poi.ss.util.SheetBuilder - useful class to build sheets from 2D arrays. I think it can be extrimely useful for tests (there are several examples in test cases ;). 2. org.apache.poi.ss.util.cellwalk package now contains classes to easily traverse cell ranges. I hope I have not reinvent the wheel here :] The good news is that after number cache implementation MS Office does not offer to save document with programmatically created charts when you open and close the document (so, number cache really affects compatibility). Plans: ====== I am planning to refactor my implementation of Series: I want to get rid of DataMarker class and introduce some kind of chart DataSource: I have found that MS Office allows you to create static charts (without any reference to cells), so DataMarker is something definitely wrong for serie composition. So I have to replace it with some kind of abstract DataSource and I am thinking about appropriate interface.
