Can somebody help me with these two linear graphics? At least some hints, how to start. I would be very greatful.

  • For our clarification: Do you want to include multiple pictures into your document or do you want to create these figures inside your LaTeX document? – Hoerbii3 Apr 21 '22 at 12:23
  • Welcome to TeX.SE :) // Have a look at https://www.ctan.org/pkg/pgf , wher you'll find the "Minimal introduction". Skimming through it will give an idea of the various concepts used. Next use the "PGF Manual" to review for more details. // For edamples and code you may also want to visit https://texample.net/tikz/examples/all/ . – MS-SPO Apr 21 '22 at 12:33
  • @Hoerbii3 I want to create these figures inside my LaTeX document – iiBum11 Apr 21 '22 at 12:44
  • Alright, then I think you can either use PSTricks or tikz (discussed here . Good luck! – Hoerbii3 Apr 21 '22 at 13:25

Here is a possibility for the first graph, with pstricks:

    \documentclass[pstricks, border=6pt]{standalone}
    \usepackage{pstricks-add}

\begin{document}

\begin{pspicture}(-2,-2)(6,6)
\psset{linejoin=1, arrowinset=0.1}
\psaxes[ticks=none, labels=none]{->}(0,0)(-2,-2)(6,6)[$ \Phi_1(t) $, -135][$ \Phi_2(t) $, -135]
\pnodes(0,0){O}(4,0){A}(0,4){B}
\ncline[linestyle=dashed]{B}{A} \naput[nrot=:U]{$\sqrt{2E_b}$}
\psline[linewidth=1.2pt, linecolor=blue]{->}(O)(A)
\psline[linewidth=1.2pt, linecolor=red]{->}(O)(B)
\psbrace[nodesepA=-1em, nodesepB=1.25em](0,-0.2 )(4,-0.2){$\sqrt{E_b}$}
\psbrace[nodesepA=-2em, nodesepB=0.5em](-0.2,4)(-0.2,0 ){$\sqrt{E_b}$}
\end{pspicture}

\end{document}

  • thank you so much for the code, it made it a lot easier for me to figure out how to do it on my own. I only had one question, how to implement this in already made \documentclass[10pt,a4paper]{article} , which library i need to include – iiBum11 Apr 21 '22 at 18:53
  • @iiBum11: You can use the code as is in the artcle class. There is single problem; pdflatex doesn't have necessary tools to make the computations required by postscript, so you to use either the standard way latex –> dvi –>ps –>pdf, or compile with xelatex --shell-escape. – Bernard Apr 21 '22 at 19:45
