Thanks a lot, Bartman.
You really helped me!

Hello

I'm using tikz-3dplot to draw a 3d coordinate system and would like to draw dots (small spheres).
With the 2d method I normally use (\draw (0,0) circle (2pt) ), the output is a circle in the xy-plane (an ellipse). Not what I want.

Anyone any idea how to solve that?

Wow, thanks for this answer. It was the answer I needed and you helped me a lot.

Hello

Having the following, working code


\begin{tikzpicture}[x=.5cm,y=.5cm]
\foreach \x in {1, 2, 3, 4, 8, 9, 10, 11} {
\foreach \y in {1, 2, 3, 4, 5}{
\fill [white] (\x,\y) circle (0.3);
\draw [TheColor] (\x,\y) circle (0.3);
}
}
\end{tikzpicture}

I would like to add a counter and an if ...
