Enhance Pie Charts to show percentage around slices about google-visualization-issues HOT 12 OPEN

I feel pieslicetext should always show, if the slice is too small, it should show outside with a line into the slice. We are doing reporting by pdf'ing the svg of google charts, and while the tooltips expose small slice values with moue over, that is not possible in a pdf, so it's hard to get good pdf reports without pieslicetext showing somewhere without a tooltip.

Yeah that would be usefull, or maybe a combination between the label and the percentage
/ amount? 

pieSliceText: "%percentage% (%value%) - %label%"

Something like that would really give us all the freedom we like :)

as @hir3npatel stated, invisible pieSliceText is a deal-breaker for pdf reports as no interaction is possible.

Following may give developers an idea about how it should seem when pieSliceText doesn't fit into the slice: http://www.highcharts.com/demo/pie-basic

Nice idea.

A workaround for now will be to add the percentage to the formatted value of each value.
So you can run some code on the data table, and setting the formatted value of a cell
with value of 30, to "30 
(20%)"

I know its not perfect, but it will work.

Thanks for the suggestion.  Although, I think the formatted value only affects the 
tooltip, which already contains the percentage.  In my scenario, I was trying to 
avoid having to click on the slice in order to see the percentage of the slice.

If you add the percentage to the formatted value, you will end up getting a duplicate
when clicking on the slice.

I wanted to get exactly the same thing as fvillaj described. It would really be more
convenient for users to instantly see the percentage around the slices instead of
having to click them one by one.

The corechart's pie chart now have an option to show the percentage on the slices (not
around them with connecting lines).

Was this functionality documented somewhere?  I can't seem to find it on any of the
API pages.  Thanks in advance.

It's documented in http://code.google.com/apis/visualization/documentation/gallery/piechart.html#Configuration_Options,
the 'pieSliceText' option, but it's actually the default, so you're supposed to see
it immediately.

@orwant or @dlaliberte is there anything in the pipeline to fix this? Activity on this repo seems very low, makes one think there's nothing going on around google charts, or no resources on it :-/
