Pie chart with only one item produces empty circle

Indeed; I just experienced a similar bug, I'm using the pie chart to give newsletters statistics about how many time the links are clicked, but in my case I don't even have the black border, the pie just vanish.

FIX:

On line 23 of http://github.com/DmitryBaranovskiy/g.raphael/blob/master/g.pie.js
replace "stroke:opt.stroke" by "stroke:opts.stroke"

Should be better :)

I have the same problem and this fix does not fix it for me, still the same 1px black border.

[impressiver]

in the minimized js file, replace "stroke:opt.stroke" with "stroke:o.stroke"

I have the same problem with one item. With the above changes nothing happens.
On firefox nothing shows up.
On Chrome the filled circle shows up, on hover it vanishes.
Any ideas why this is happening?

I resorted finally to do the changes as above in g.pie.js setting it to stroke:o.stroke though it didnt fix the problem. I set one of the other data as well to a fraction 0.001 and was able to get the chart shown as needed with 100% for the one which needs to show up but there is a very fraction which doesnt effect the chart for now.

Maybe this might help someone having a similar problem.

The problem is that according to w3c's SVG spec (http://www.w3.org/TR/SVG/implnote.html#ArcOutOfRangeParameters) if the start and endpoint match, then no arc is drawn.

To anyone who needs to just put a dot (100% of a value for example):

The following commit solves this problem, as well as adding a couple of features for the pie chart. My group is extending this library for our cross-platform graphing library.
