Hi,
this is still / again concerning the evaluation `project'.
The result of this ranking had been previously created with Corel Draw (?)
and look like this
--------------------------
Title
+------------------+ 100%
| Name_1 |
| Name_2 |
~ ~
| Name_n-1 |
| Name_n |
+------------------+ 25%
Footnotes/remarks
-------------------------
The name-pane is coloured green(100%) to red (25%) via yellow using a gradient
shading. Is it possible to access with MP and/or direct writting the PS-3 /
PDF-1.3 shading operator? (I think I once saw an exaple, probably for testing GS
(due in a few weeks, current is 5.99-fix1).
Second problem: Since the names (should) cover the complete colour-pane, arrows
are currently drawn from the name to the percental position on the right edge.
How can this best achived?
(I'll use a PERL-Script, which reads the name and %-value, so I can do quite
some calculation in it.)
Groetjes,
Tobias
PS: I think if I've done this, I can ship a complete evaluation/ranking script
package for university departments (web interface, fill-out forms, etc) ;-)

You wouldn't ask if you wouldn't know if it was possible, would you?
Actually, this is already half a year old stuff. I attached the file, so
that you (and others) can test it; you need acrobat 4 or gs>5.50 or so.

Take a look at the support module I'll send you. It's just a matter of
defining a few MPgraphics. It is not finished, since matthew baker will
first have to work out some decent arbitrary shading schemes (for which I
lack the math basics). These are only simple shades.

Well. Wrap it into an article and taco will certainly publish it in the maps.
