I have a problem regarding making a lots of grid i tikz.
my code is as follows:
\begin{tikzpicture}
\path[use as bounding box,draw] (12,18) rectangle (0,0);
\foreach \x in {0,2,4,8}
\draw[black] (0.999+\x,17) grid[step=0.2] (2+\x,15.999);
\draw[->] (3.5,15.5) -- (3.5,13);
\draw[->] (9.5,15.5) -- (9.5,13);
\foreach \x in {2,4,6,8}
\draw[black] (0.999+\x,12) grid[step=0.2] (2+\x,10.999);
\draw[->] (6.5,10) -- (6.5,9);
\draw[black] (5.999,8.100) grid[step=0.2] (7,7.099) node {};
\end{tikzpicture}
One can clearly see that the grid in the third row are not drawn corretly.
Hope that any of your can help.
\draw[black] (5.999,8.100) grid[step=0.2] (7,7.099) node {};
should be\draw[black] (5.999,8.100) grid[step=0.2] (7,6.99) node {};
node {}
?
