I know how to make a rectangle and fill it.

But what shoud be done to hatch this rectangle with thin 45 degree inclined line with 2mm gap.

\documentclass{article}
\usepackage{tikz}

\begin{document}

\begin{tikzpicture}
%\draw (0,0) rectangle (2,4);
\fill[blue] (0,0) rectangle (2,4);

\end{tikzpicture}

\end{document}

Thank you Altermundus,

I want to hatch area under the curve. But I am unable to use your code as i did with

[pattern=north west lines, pattern color=blue]

Please give little explanation for your code so that i can use it.

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{patterns}

\begin{document}
\begin{tikzpicture}
\draw[pattern=north west lines, pattern color=blue] (0,0) rectangle (2,4);
\end{tikzpicture}

\begin{tikzpicture}
\draw [thick,pattern=north west lines, pattern color=red] (1,0)--(1,1) to [bend left] (4,4) -- (4,0) --cycle;
\end{tikzpicture}

\end{document}

Actually, I don't have a clue what you want. Could you probably add a picture (handdrawn or whatever) of what you want to achieve? –  Tom Bombadil May 5 '12 at 9:48

You can use the library patterns. For example:

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{patterns}

\begin{document}
\begin{tikzpicture}
\draw[pattern=north west lines, pattern color=blue] (0,0) rectangle (2,4);
\end{tikzpicture}

\end{document}

which gives you as result:

You find much more in the documentation (pgfmanual): chapter 41 Pattern Library.

Thanks Claudio Fiandrino –  sandu May 5 '12 at 9:59
    
@Claudio. Do you know how to apply this to the fill in large typeface? –  Nicholas Hamilton Aug 29 '13 at 12:00
    
@ADP: what do you mean for large typeface? –  Claudio Fiandrino Aug 30 '13 at 12:26
    
@Claudio say 100pt font used in a chapter page. –  Nicholas Hamilton Aug 30 '13 at 13:58
    
@ADP: ultimately you want to apply a pattern to a text, is it? In that case I don't know (notice, the font size does not influence at all the applicability), but I guess it won't be so much easy. –  Claudio Fiandrino Aug 30 '13 at 14:06

Not exactly an answer but two examples of code to get a crosshatched rectangle without pattern. This code was necessary with the first version of pgf/tikz.

It is possible to get a better code with clip . The second one use fp.

\documentclass[11pt]{scrartcl}
\usepackage{tikz,ifthen,fp,calc}

\makeatletter
\newlength{\tkz@size}

\newboolean{tkz@rect@inv}\setboolean{tkz@rect@inv}{false}

\def\tkzhachrect[#1](#2,#3)(#4,#5){%
% A(#2,#3) D(#4,#5)

\draw (#2,#3) rectangle (#4,#5) ;
\setboolean{tkz@rect@inv}{false}
\setlength{\tkz@hachsep}{#1 cm}% sep des hach.
