Document Classes ⇒ PSTricks | Plot of a Gauss Curve

[vdhvu]

Could you help me using PSTricks to draw a bell-shaped curve with filling two tails as in the attached picture?

Thank you.

This is not so complicated as it seems to be. All you need is the pstricks-add package and the pst-func package.

Code: Select all

\documentclass{minimal}
\usepackage{pst-func,pstricks-add}

\begin{document}
  \begin{pspicture}[showgrid=false](-5,-1)(5,5)
    \psset{yunit=4cm,xunit=2}
    \pscustom[linestyle=none,fillcolor=red,fillstyle=solid]{%
      \psline(-1,0.125)(-1,0)(-1.75,0)
      \psGauss{-1.75}{-1}
    }
    \pscustom[linestyle=none,fillcolor=red,fillstyle=solid]{%
      \psGauss{1}{1.75}
      \psline(1.75,0)(1,0)(1,0.125)
    }
    \psaxes[Dy=0.25,linecolor=blue]{->}(0,0)(-2,0)(2,1.25)
    \uput[d](2,0){x}\uput[r](0,1.25){y}
    \psGauss[sigma=0.5]{-1.75}{1.75}
  \end{pspicture}
\end{document}

The \psGauss command is provided by the pst-func package. Refer to the manuals of pst-func, pstricks-add and at least pstricks for further information.
