[xwiki-devs] [Proposal]Chart macro - Create new com.xpn.xwiki.plugin.charts.source.DataSource for it

Hi guys, In order to implement the chart macro (http://jira.xwiki.org/jira/browse/XWIKI-2883) , i propose the following: - Create a new TableBlockDataSource which implements the com.xpn.xwiki.plugin.charts.source.DataSource and which will take data from a table contained within a Wiki2.0 document. - Use the existing ChartPlugin for aquiring this new data source and generate the graph. This new datasource, in order to be compatible with the chartPlugin, gets its parameters via a Map<String, String>. So I'm thinking of passing the current document and the table number as strings encoded in such a Map and then, in the datasource parsing the document and getting its DOM tree and then extracting the data from it. What do you think about this approach? Tnx, Dan
