I am currently having trouble while adding transparency to my pie charts. 
I can't set using `FaceAlpha` or `EdgeAlpha` and using alpha alone kind of rips the edges of the chart when compiling the eps file.

Any tips?

```
figure;
subplot(1,2,1)
h=pie3(P1,[0 0 0 1 1])
set(h,'EdgeColor','none','LineStyle','none')
hold on
colormap cool
hold on

subplot(1,2,2)
h=pie3([PF PG],[1 0 ],{'X1','X2'})
set(h,'EdgeColor','none')
colormap cool
%alpha(0.5)

print teste -depsc2 

```
