[Tex/LaTex] Quarterly filled circle symbol

Question

For a comparison table I am using the symbols of wasysym which gives me an empty circle, a full circle and also half filled circle.

However I would rather use a more fine grained sale and for this I need also a quarterly filled circle and a circle which is filled by 3/4.

Does anyone know if such symbols exist in any LaTeX package?

Answer 1

Not the best macro in the world, but perhaps something like

\usepackage{tikz}

\newcommand{\pie}[1]{%
\begin{tikzpicture}
 \draw (0,0) circle (1ex);\fill (1ex,0) arc (0:#1:1ex) -- (0,0) -- cycle;
\end{tikzpicture}%
}

And an example

Hello world \pie{90} \pie{120} \pie{240} \pie{270}

Output:
