Changing colors and legend

[JulongWei]

Hi,

Thanks for your providing useful package. That makes life easier once again.
But I have some questions to ask you:
(1) Could We set the different colors of parts of each pie using your function or through scale_colour_manual?
(2) larger number has a bigger pie plot. Could we provide the legends by ourselves, legend name and size?

Best,
Julong

Because the package effectively creates a boxplot and circularizes it, instead of colour (which is defines the borders of the box / pie chart) you can change the colour using
scale_fill_manual
