Graphics, Figures & Tables ⇒ Plot e^x with PSTricks

[coachbennett1981]

I am trying to plot this function and have looked at several PStricks modules but have had no luck graphing e^x. I can do ln(x) just fine..

Anyone have suggestions?


Thank you

Nick

\documentclass{minimal}
\usepackage{pstricks-add}

\newcommand*{\PSTeuler}{2.7182818}

\begin{document}
  \begin{psgraph}(0,0)(-5,0)(5,8){10cm}{!}   % x-y-axis with same unit
    \psplot[algebraic=true,linecolor=red]{-5}{2}{\PSTeuler^x}
  \end{psgraph}
\end{document}

How do you know so much??? Thank you so much!

When I use your code, I get the following error.. I have been told I need to update my PStricks, but I don't know how.. I am simply not that advanced..

Undefined controls sequence
<argument>..psplot \ifPst@algebraic (\PSTeuler^x) \ifx \psk@PlotDerivative...

Reading the related manuals helps a lot. The rest is practical application (although I switched to pgf/tikZ).

You just need an update [1]. That's it.

I use TexShop.. So I don't think that will be the same for me.

So you will have to do that manually according to the TeX Directory Structure (TDS) standard. I'm not familiar with the LaTeX system on a Mac. But there should be TeX Live 2009 available for your machine.

It seems that your version doesn't accept the algebraic option. For the present you can try to plot the function using a postfix expression.
