I have the code:
\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{pgf-pie}
\begin{document}
\begin{tikzpicture}
\pie[text=,before number=, after number=,color={blue!33.33, blue!33.33, white!33.33}]
{33.33, 33.33, 33.33}
\end{tikzpicture}
\end{document}
which produces the output
How can I hide the numbers (33.33)?

pgf-pie? Something like:\filldraw[fill=blue!20!white, draw=black] (0,0) -- ( 0:4cm) arc ( 0:120:4cm) -- (0,0);– Thruston Apr 20 '17 at 16:46before number=\pgfsetfillopacity{0.0}is a solution for hiding the numbers only, leaving the labels visible. – Hermann Dec 06 '19 at 15:57
