Hi David,
Do you mean a pie and bar chart for every feature on the map? There is some
work in the diagram-branch that allows generating pie- and bar diagrams on
maps. It is not finished completely and thus not in trunk, but can already be
used. Check out the branch with:
svn co
https://svn.qgis.org/repos/qgis/branches/diagram-branchIn the branch, open the plugin manager and select the 'diagram overlay'
plugin. After this, there is a new tab in the vector layer properties dialog
where the settings for diagrams may be entered.
Regards,
Marco
