Graphics, Figures & Tables ⇒ Advanced Plotting

[Henryy]

Hello LaTeX Comunnity

Today I come here facing a new problem.

I have been getting some experience using LaTeX. However, I'm not still capable of plotting propperly.

I need to plot this function

plot.gif (1.7 KiB) Viewed 2073 times

and I really don't have a barely idea on how to do it. I've reading some tutorials but im still blank.
Please give me some tips/ideas on plotting this.

Thanks in advance and have a good night.

Hi Henryy,

I have been getting some experience using LaTeX. However, I'm not still capable of plotting propperly.

What did you try? Did you make any plot?

I've reading some tutorials but im still blank.

What did you read? And about which plotting tool: PSTricks, gnuplot, TikZ or pgfplots? I would recommend the latter, have a look at the pgfplots manual.

what should (-1)^2/3 mean? It is always the same as 1

The first image is for c1=0.1 and the second for c1=2. Run the example with xelatex or latex->dvips->ps2pdf

Code: Select all

\documentclass{article}
\usepackage{pst-plot}
\begin{document}

\pstVerb{
 /c1 0.1 def 
 /sqrt3 { dup 0 lt {neg 1 3 div exp neg }{ 1 3 div exp } ifelse } def
 }
\begin{psgraph}[arrows=->](0,0)(-5,-1)(5,8){10cm}{8cm}
\psplot[algebraic,linecolor=red,
  linewidth=2pt,plotpoints=1000]{-5}{5}{sqrt3(6*c1+x*(2*x*x+21*x+18))/2^(1/3)}
\end{psgraph}

\end{document}
