Graphics, Figures & Tables ⇒ Postfix expression and PSTricks

[coachbennett1981]

I am trying to graph a simple exponential function in PSTRICKS. I have used what I believe is called postflix to plot y=2^x, as

Code: Select all

2 x exp

. How could I graph 2(.5)^x? I am messing with the graph but can't see to get it right.. I have tried the following

Code: Select all

2 .5* x exp

, but it does not give me what I need..

thank you in advance for any suggestions..

Figured it out

.5(5)^x= 5 x exp .5 mul

[localghost]

Code: Select all

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

\begin{document}
  \begin{psgraph}(0,0)(1,3){2cm}{!}   % x-y-axis with same unit
    \psplot[algebraic=true,linecolor=red]{0}{1}{0.5*5^x}
  \end{psgraph}
\end{document}
