I'm trying to draw a smooth third grade spiral (r^3 = a^3\cdot \varphi
) over $60\times 60$mm
grid and I'm getting the "Dimension too large"-error if I set $a > 320$
but I need to fill the grid area completely:
\begin{tikzpicture}[x=1mm, y=1mm]
\draw[step=1, line width=0.1mm, opacity=0.3] (-30, -30) grid (30, 30);
\draw [domain=0:50, variable=\t, samples=1000]
plot ({\t r}:{pow(320*\t, 1/3)});
\end{tikzpicture}
Is there any way to avoid this error?
