Graphics, Figures & Tables ⇒ How to draw multiple Rectangles from input data file

[taniamalik]

Hi
I want to draw set of rectangles on axis based on input file. My .tex file should be some thing like that

Code: Select all

\documentclass{article}
\usepackage{tikz,pgf}
\usetikzlibrary{plotmarks}
\usepackage{pgfplots, pgfplotstable}
\usetikzlibrary{fit,calc}
\begin{document}

\begin{tikzpicture}
\begin{axis}[
width=8cm,
height=8cm,
scale only axis,
xmin=-1, xmax=20,
ymin=-1, ymax=20,
xlabel={i},
ylabel={j},
title={Hi}]
\pgfplotstableread{data.dat}\table;
for each row in table
if (\gg=0)
{
 \draw [black, fill=blue, thick] (axis cs:\x,\y) rectangle (axis cs:\xx,\yy);
    \end{axis}
else if (\gg=1)
\draw [black, fill=red, thick] (axis cs:\x,\y) rectangle (axis cs:\xx,\yy);
    \end{axis}
else if (\gg=2)
\draw [black, fill=red, thick] (axis cs:\x,\y) rectangle (axis cs:\xx,\yy);
    \end{axis}
	\end{tikzpicture}
	\end{document}

Where as my input file look like

Code: Select all

%% data.dat 
x	y	xx	yy	gg	
0	0	5	4	0	  
0	4	5	9	1
0	9	5	13	0
0	13	5 	16	1
5	0	9	5       2

Plz help me out how can I draw them.
Thanks

Hi taniamalik.

Welcome to the board! (I hope a welcome greeting i not for moderators only...)

I do not know TikZ, but what I do know, is that you can (1) edit your post, (2) mark all the code belonging to your TeX file, and (3) click the botton "Code" above the editing window. Then the code will be nicely formatted.

Update
Cross-posting is no-go unless you link properly (if you ask me)!
