I'm looking for a code drawing the below picture with TikZ if it is possible:

I just need the graph in the middle, i.e. there is no need to also include the text and/or equations. Simply the plot together with the axes would be more than fine.

From the suggestions of the comments I found this piece of code online that I copied but somehow it refuses to work: The source that I stole it from was a PDF and when I pasted it into a TeX-editor there were a lot of unnecesary blank space and other stuff. I suspect that's why it didn't work.

% Codice di Spike
\documentclass[a4paper ,11 pt]{article}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}[y ={(0.866 cm,-0.5 cm)} , x ={(-0.866 cm ,-0.5 cm )},z ={(0 cm ,1 cm )}]
\coordinate(O) at (0 , 0 , 0);
\draw [-latex ](O) -- +(2 , 0 , 0) node [ left ]{$ x $};
\draw [-latex ](O) -- +(0 , 7 , 0) node [ right ]{$ y $};
\draw [-latex ](O) -- +(0 , 0 , 2) node [ above ]{$ z $};
 % onde e vettori che indicano l? intensita ? dei campi
\draw [thick,color=teal,variable=\x,samples at ={0 ,0.1 ,... ,6.3}] 
    plot ({ - sin (2* \x r )},\x ,0) node [ anchor = north ]{$ \vec { E }$};
\foreach \x in {0.25 , 0.5 ,... ,6}
    \draw [ color =teal , - latex ] (0 , \x ,0) -- ({ - sin (2* \x r )} , \x ,0);
    \draw [thick , color = purple , variable =\x , samples at ={0 ,0.1 ,... ,6.3} ]
    plot (0 , \x ,{ - sin (2* \x r )}) node [ anchor = west ]{$ \vec { H }$};
\foreach \x in {0.25 , 0.5 ,... ,6}
     \draw [color = purple , - latex] (0 , \x ,0) -- (0 , \x ,{ - sin (2* \x r )});

    You can use Mark Wibrow's amazing answer to get started. If you get stuck, feel free to ask a more concrete question.

    Actually, people are saying precisely that the site should not be regarded as a 'give me the answer' black box.

    @LoveLearning: Thanks for adding the code to the question. However, "somehow it refuses to work" is not very helpful. Do you get an error message? If so, what error message? Or is the output not what you expected? If so, how does it differ from your expectation?

With TikZ

\documentclass{article}
\usepackage{tikz,bm}
\usepackage[raggedrightboxes]{ragged2e}
\begin{document}
\begin{center}
  \begin{tikzpicture}[x={(-10:1cm)},y={(90:1cm)},z={(210:1cm)}]
    % Axes
    \draw (-1,0,0) node[above] {$x$} -- (5,0,0);
    \draw (0,0,0) -- (0,2,0) node[above] {$y$};
    \draw (0,0,0) -- (0,0,2) node[left] {$z$};
    % Propagation
    \draw[->,ultra thick] (5,0,0) -- node[above] {$c$} (6,0,0);
    % Waves
    \draw[thick] plot[domain=0:4.5,samples=200] (\x,{cos(deg(pi*\x))},0);
    \draw[gray,thick] plot[domain=0:4.5,samples=200] (\x,0,{cos(deg(pi*\x))});
    % Arrows
    \foreach \x in {0.1,0.3,...,4.4} {
      \draw[->,help lines] (\x,0,0) -- (\x,{cos(deg(pi*\x))},0);
      \draw[->,help lines] (\x,0,0) -- (\x,0,{cos(deg(pi*\x))});
    }
    % Labels
    \node[above right] at (0,1,0) {$\bm{E}$};
    \node[below] at (0,0,1) {$\bm{B}$};
  \end{tikzpicture}

    \begin{tabular}{r@{${}={}$}p{.8\linewidth}}
      $E$ & electric field amplitude \\

    \end{tabular}
  \end{minipage}%
  \begin{minipage}{.5\linewidth}
    \[
      c = \frac{1}{\sqrt{\mu_0 \varepsilon_0}}
    \]
    \begin{tabular}{r@{${}={}$}p{.8\linewidth}}
      $\mu_0$ & magnetic permeability in a vacuum, $\mu_0 = 1.3\times10^{-6}\,\mathrm{N/A^2}$ \\
