[Matplotlib-users] Percentage in pie in e.g. white instead of black

[Werner F. B. <wer...@fr...>]

I would like to have the percentage values shown in white instead of in 
black within a pie chart.

I figured I could do something like:

        def reColor(percent):
            "I am lost here on how to format the percentage and change 
the color"

axes.pie(values, labels=labels, autopct=reColor, shadow=False, 
colors=colors)

I thought I could use a mpl.text.Text but I only get the percentage in 
"reColor".

Looked at the gallery and tried to based it on the "barchart_demo2.py" 
example without success.  Although would prefer not to have to loop 
through the text.Text instances and figure out which ones are a 
percentage and then color them - but I guess that would be one way of 
doing it but it looks a bit odd to me.

Thanks for any tips

The following code is doing what I want, but it does not feel right.

         myPie = axes.pie(values, labels=labels, autopct=u'%1.0f%%', 
shadow=False, colors=colors)
         
        for x in myPie[2]:
             x.set_color('w')

Is there really no "cleaner" way of doing this?
