CPTPieChart pie with one element

[Stephen Korow]

When I create a CPTPieChart and it has only one element, the color of the pie slice, in this case the entire circle, does not display.  This is also true of the example code.  Is there a way around this?  

Thanks.

For the demo app, the SimplePieChart class, if I don't use a gradient it fills.  If I user the CPTGradient for the overlayFill property, I get the background; not the fill color.  I tried switching the gradientType to a Axial, as suggested in a previous thread.  The fill color still didn't display.

Try a non-zero data value for the single data value. That works for me in the SimplePieChart on the release-2.3 branch.

It doesn't make sense to plot a pie chart with a net total value of zero. The width of each slice is the fraction of the total value. When the total is zero, you get a divide-by-zero and an undefined slice width. That's why no slices are drawn in that case.

Thanks for the response.  However, I am not using a zero value data element.  Using the SimplePieChart class as an example, the generateData class creates a three element array 

     self.plotData = @[@20.0, @30.0, @60.0];

I changed it to a single element array:

     self.plotData = @[ @60.0];

This change will recreate the problem.

make that "generateData method", not "generateData class".

I was using release 2.2.  I tested on the 2.3 branch and it is working as expected.  Problem solved.  Thank you.
