[pstricks] bardiag - plotting negative bars

[Henning Haida]

Dear all,

I would like to plot negative bars in a bardiagram using bardiag. Is that
possible? Please see (the not so minimal) example below.

A second questions is: In bardiag.pdf there is written

	\bardiagrambegin{diagheight}{diagwidth}...

Could it be that height and width are mixed up?

Best Regards,

Henning
