As it's my first question, I want to say hello first!
I am using [grid with coordinates] code from Andrew Stacey answer (link) for How can I show coordinates by grid in TikZ automatically?.
I modified it a bit and tried to acquire different major/minor lines xstep and ystep, I ended with:
\documentclass{article}
%\usepackage{pgfplots}
\usepackage{tikz,pgfplots}
\makeatletter
\def\grd@save@target#1{%
\def\grd@target{#1}}
\def\grd@save@start#1{%
\def\grd@start{#1}}
\tikzset{
grid with coordinates/.style={
to path={%
\pgfextra{%
\edef\grd@@target{(\tikztotarget)}%
\tikz@scan@one@point\grd@save@target\grd@@target\relax
\edef\grd@@start{(\tikztostart)}%
\tikz@scan@one@point\grd@save@start\grd@@start\relax
\draw[minor help lines] (\tikztostart) grid (\tikztotarget);
\draw[major help lines] (\tikztostart) grid (\tikztotarget);
\grd@start
\pgfmathsetmacro{\grd@xa}{\the\pgf@x/1cm}
\pgfmathsetmacro{\grd@ya}{\the\pgf@y/1cm}
\grd@target
\pgfmathsetmacro{\grd@xb}{\the\pgf@x/1cm}
\pgfmathsetmacro{\grd@yb}{\the\pgf@y/1cm}
\pgfmathsetmacro{\grd@xc}{\grd@xa + \pgfkeysvalueof{/tikz/grid with coordinates/major step x}}
\pgfmathsetmacro{\grd@yc}{\grd@ya + \pgfkeysvalueof{/tikz/grid with coordinates/major step y}}
\foreach \x in {\grd@xa,\grd@xc,...,\grd@xb}
\node[anchor=north] at (\x,\grd@ya) {\pgfmathprintnumber{\x}};
\foreach \y in {\grd@ya,\grd@yc,...,\grd@yb}
\node[anchor=east] at (\grd@xa,\y) {\pgfmathprintnumber{\y}};
}
}
},
minor help lines/.style={
help lines,
gray,
line cap =round,
xstep=\pgfkeysvalueof{/tikz/grid with coordinates/minor step x},
ystep=\pgfkeysvalueof{/tikz/grid with coordinates/minor step y}
},
major help lines/.style={
help lines,
line cap =round,
line width=\pgfkeysvalueof{/tikz/grid with coordinates/major line width},
xstep=\pgfkeysvalueof{/tikz/grid with coordinates/major step x},
ystep=\pgfkeysvalueof{/tikz/grid with coordinates/major step y}
},
grid with coordinates/.cd,
minor step x/.initial=.5,
minor step y/.initial=.2,
major step x/.initial=1,
major step y/.initial=1,
major line width/.initial=1pt,
}
\makeatother
What I need now is to specify xstep and ystep in actual tikzpicture, e.g. in code below I want to pass xstep and ystep (for minor and major lines separately) so that Fig. B gets major lines xstep =0.2.
\begin{document}
\begin{figure}
\centering
\begin{tikzpicture}[xscale=1,yscale=2]
\draw (0,0) to[grid with coordinates] (5,1);
\end{tikzpicture}
\caption{A}\label{fig:sphere}
\end{figure}
\begin{figure}
\centering
\begin{tikzpicture}[xscale=5,yscale=2]
\draw (0,0) to[grid with coordinates] (1,1); %major step x =0.2
\end{tikzpicture}
\caption{B}\label{fig:sphere}
\end{figure}
\end{document}
I can't guess how to pass the parameters.
\draw (0,0) to[grid with coordinates,/tikz/grid with coordinates/major step x=.5] (5,1);perhaps ... – Alain Matthes Apr 16 '13 at 22:28
