\section{Use of \tkzcname{tkzGrid}} \hypertarget{grid}{} \begin{NewMacroBox}{tkzGrid}{\oarg{local options}\parg{$x_A~;~y_A$} \parg{$x_B~;~y_B$}}% A few changes for this macro. First of all, to simplify currently the color of the thinnest grid is determined automatically from the main grid, same process for the thickness. This behavior can be modified using styles. \begin{tabular}{lll}% options & default & definition \\ \midrule \TAline{\parg{$x_A~;~y_A$} \parg{$x_B~;~y_B$}}{(xmin,ymin)(xmax,ymax)} {grid pattern} \end{tabular} \begin{tabular}{lll}% options & default & definition \\ \midrule \TOline{sub}{true} {asks for a sub-grid } \TOline{color}{darkgray}{main grid color} \TOline{subxstep}{0.2} {the step of the subgraduations for the abscissa axis} \TOline{subystep}{0.2}{the step of the subgraduations for the ordinate axis } \TOline{line width}{0.4pt} {main grid line thickness} \bottomrule \end{tabular} \medskip Default values can be changed in the configuration file or by macros. The color of the second grid is the same as the main grid, but less intense (by default |gray!50|). Same behavior for the line thickness (by default |0.75 of line width|). See the examples to change this behavior. \end{NewMacroBox} \subsubsection{\tkzcname{tkzGrid} and the option \tkzname{sub}} The option \tkzname{sub} allows you to display a finer secondary grid. It is preferable to run \tkzcname{tkzGrid} first, to prevent the grid from being overlapped with other elements. \begin{tkzexample}[latex=8cm,small] \begin{tikzpicture} \tkzInit[xmax=4, ymax=2] \tkzGrid[sub] \tkzAxeXY \end{tikzpicture} \end{tkzexample} \subsubsection{Option \tkzname{sub}} The option \tkzname{sub} allows to display a finer secondary grid.
