Description Davide Imbeni 2008-02-19 17:07:00 UTC 
It would be nice if it was possible to address single slices and single bars in graph objects so as to allow e.g. gnucash developers to add support for slice/bar specific tooltips and/or callback on mouse click.
This would enable to restore an old feature of gnucash reports (once based on guppi).

Comment 1 Jody Goldberg 2008-02-24 16:32:50 UTC 
Single pie slices have been supported for a long time via
        GogObject *singleton = gog_object_add_by_name (series, "Point", NULL);

BarCol does not support singletons now but should not be too hard to add.

There are some mechanisms for custom tooltip and actions via GogObjectView::toolkit.  Please give that a look to see if it is strong enough for your needs.   For now I'll slim this bug down to focus on just the singletons in bar/col.
Comment 2 Jean Bréfort 2008-06-21 12:33:21 UTC 
Added support for singletons in BarCol in trunk.
Comment 3 Jody Goldberg 2008-06-21 13:26:50 UTC 
And you've added support to XY and bubble.

I don't think singletons make much sense for Area, Surface or Radar plots.  Which leaves lines.
Comment 4 Jean Bréfort 2008-06-21 13:37:41 UTC 
Yes for lines we might allow a marker change. Note that for XY, we have an empty Style page. I need to fix that.
Comment 5 Jody Goldberg 2008-07-14 12:26:53 UTC 
The singleton support has been in for a while now, and I have not heard back whether or not the ::toolkit support was strong enough to support your goals.  If not please open a new bug with something explicit.

Thanks
