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.

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.
