Exporting Vaadin chart in Excel

How do I export vaadin chart in Excel?


Vaadin Charts renders client-side, but with some tricks you can do it server-side. Matti made a blog article about it :
Adding some Batik magic (TranscoderInput) would let you get an image from that, wich you can insert onto an excel file with some java library (for instance : http://jexcelapi.sourceforge.net).

… but basic question could be : isn’t it easier to export data to an excel file (or template) and let excel make the graph ?
