mpost problem [graph]

[Marc van Dongen]

Hello there,

Again, this is one of my mpost and non-ConTeXt postings.
Appologies to those who are offended.

I would be delighted if somebody could help me out
with the following. I am using the mpost program as
appended below. It produces an eps which doesn't show
the minus-signs in the formula
 $\upb_{{\cal{D}}} - \avg_{{\cal{D}}}$
and on the vertical axis of the graph that is drawn.

I must have overlooked something. Any suggestions?
Thanks a mille advance.

You may try different values of prologues, say prologues := 0 ; after
loading mp-tool. 

Otherwise, use mptopdf to convert the mp graphic to pdf and view that one
[or convert it back to ps afterwards]. 

BTW, i have an experimental extension to the graph macros doing real tex
instead of pseudo tex.

That didn't work. I tried 0, 1, 2.

mptopdf. Isn't that a tex-thingy? I don't have mptopdf
at the moment. I'll try to find it over the weekend and
see if that solves the problem.  I recll I had it some
time ago. Possibly as part of a ConTeXt distribution.

Now that would be interesting...
Thanks for the suggestions.

Marc

It does work! I must check out my ghostview. If I include the
eps (yes I am not producing pdf at the moment) it comes out
fine. Thanks.
