Why does a piece of a pie chart with a higher value appear smaller in size than a piece with a lower value?

[brettr16263145]

I'm trying to create a pie chart with a breakdown of revenues for a year from highest to lowest.

440,719

245,182

69,138

34,903

29,922

26,855

18,595

8,444

4,337

3,909

3,887

For some reason, the 4,337 pie piece appears as half the size of the 3,909 piece. I've converted these costs to percentages to see if that worked:

49.75

27.69

7.80

3.94

3.38

3.03

2.10

0.95

0.49

0.44

0.43

Same problem. 0.49 appears smaller than 0.44. I understand that a pie-chart is just a rough visualization but it should at least appear the same size, right?

Why is this happening? What is causing this discrepancy? Is there a work-around?

Please show screenshots that illustrator your problem.

If you want people to experiment with your problem then upload the file and post a link here.

Also: Please show your options for the graph.

Thanks, Monika. Here are screenshots. The graph comes out the same if you input $ amounts or as %.

This has been around for a very long time, and I believe a mathematical programming error. Possibly rounding or division by odd number of pie pieces. I pasted in your numbers and quick sampled some of your colors.

I then added an extra number "L"

@ohmath might be able to help get this looked at by Adobe.

Would be great if they updated graphing in Illustrator and give us 3D charts, better data editing, color group fills and more. If the Illustrator team back in the 90s with Terri & Russell could give use features worth upgrading to, I think it is time we seen what this new millennium team can actually do or not do.

This is by no means a fix but if you're in a time-crunch like I am (I'm not holding my breath for Adobe to fix this egregious bug) I suggest you find an online pie-chart creator such as www.meta-chart.com where you can export as SVG and then tweak styling in Illustrator.

So very frustrating considering how much Adobe CC costs—you'd think you'd at least be paying for a program that can create a simple pie chart when a free-to-use website has figured it out.

And if anyone knows how to get Adobe to actually address this asinine fault in programing, please share.
