PieChart as the tooltip in a stacked AreaChart

[Sam Halliday]

Hi all,

It is possible to set the 'focusTarget' of a ComboChart to be
'category' meaning the tooltip will list all the values at that row.

If 'isStacked' is true (or, I suppose, even if it is not) it would be
really great if the tooltip displayed a PieChart instead of listing
the values. Is this possible? I can't seem to work out how to set the
tooltip dynamically like this.

Regards, Sam

I'm not quite sure what you mean by your first question, but it sounds like you are looking for something similar to the "domain" data role:  http://code.google.com/apis/chart/interactive/docs/roles.html

As to your second, I don't believe there is any way to put a PieChart (or anything other than text, for that matter) inside a tooltip.  You could create a Pie chart along side the main chart and link them together, though.

Hmm, thanks - that's what I had figured. Unfortunately that isn't
going to look great so I'll stick to tooltips. (because the tooltips
are all in SVG, I can't even edit the element manually to do this)
