Graphics, Figures & Tables ⇒ tikZ | A simple Diagram

[thinkpadT]

Hi everyone,

I just started using tikZ together and find it to be very suitable for my needs. I wanted to draw the attached diagram, had a difficult time. I would appreciate any starting help.


Thanks a lot in advance

Then you can for sure show your recent efforts in form of a concrete code example. It's easier and faster to correct some presented code than to write something from scratch.


Best regards and welcome to the board

hi Thorsten,

you are totally right about that. so here is my humble code that worked for me.
I need to place the caption at right place, how can i achieve that ?
Another thing that would be nice, if the diagrams were not so small, i want them to be one page large, can i get some help on that, too

Code: Select all

\documentclass{article}

\usepackage[latin1]{inputenc}
\usepackage{tikz}

\begin{document}
 \begin{tikzpicture}
  \begin{tikzpicture}
   \draw[gray,fill=gray!10] (-1.5,0.5) rectangle +(3,-1);
   \fill[blue,path fading=east] (0:0) -- (10:6) -- (-10:6) -- cycle;
   \fill[blue,path fading=west] (0:0) -- (-10:-6) -- (10:-6) -- cycle;
   \fill[red,path fading=east] (0:0) -- (3:6) -- (-3:6) -- cycle;
  \end{tikzpicture}
\end{document}

Thanks very much
Fawad

Hi,

See whether the following code is suitable for you:

Code: Select all

\documentclass{article}

\usepackage{tikz}

\begin{document}

\begin{tikzpicture}
  %\draw[help lines,step=.5,lightgray] (-5,-2) grid (5,2) ;

  \path [draw=black,fill=red!70] (-5,1) -- (0,0) -- (-5,-1) -- cycle ;
  \path [draw=black,fill=red!70] (5,1) -- (0,0) -- (5,-1) -- cycle ;
  \path [draw=black,fill=blue!70] (5,0.3) -- (0,0) -- (5,-0.3) -- cycle ;

  \draw [gray] (-1,-.4) rectangle (1,.4) ;
  \node [below] at (0,-0.5) {gas cell} ;

  \draw (-3,0) -- (-3,1.5) node[above] {\small pump laser} ;
  \draw (3,0) -- (3,1.5) node[above] {\small higher harmonics} ;
  
\end{tikzpicture}

\end{document}

Regards.

And it would be very kind if you post the complete solution so that others with the a similar problem who come here by search engine can benefit.

hi localghost,
For sure, here is the code to the final result i have got

Code: Select all

\documentclass[landscape]{article}

\usepackage[latin1]{inputenc}
\usepackage{tikz}
\usetikzlibrary{fadings}
\begin{document}

 \begin{tikzpicture}[domain=1:1]
	
%------------------fundamental and harmonics
  \fill[blue,path fading=east] (0:0) -- (10:6) -- (-10:6) -- cycle;
  \fill[blue,path fading=west] (0:0) -- (-10:-6) -- (10:-6) -- cycle;
  \fill[red,path fading=east] (0:0) -- (3:6) -- (-3:6) -- cycle;
  
%-----------captions
  \draw (-3,0) -- (-3,1.5) node[above] {\small pump laser} ;
  \draw (3,0) -- (3,1.5) node[above] {\small higher harmonics} ;
  \node [below] at (0,-0.5) {gas cell} ;

%----------transparent gas cell
  \begin{scope}[fill opacity = 0.3]
  \draw[gray!25,fill=gray!10] (-1.5,0.5) rectangle +(3,-1);
  \end{scope}

 \end{tikzpicture}

\end{document}

Thanks again everyone
