What plotting program?

[Daniel Farrell]

Hello,

In you opinion what plotting programe made this contour plot,
http://solardat.uoregon.edu/download/misc/EugeneContour.pdf

I know I could just contact the author (I think I will) but I wanted  
to point this out to the list because it looks really nice. I looks  
nicers than a gnuplot contour plot. I like the labels appearing along  
the contour lines. For certain types of contour plots (where the  
changes over the surface a smooth) I think this better represent the  
data as apposed to using colours and a colour map bar.

What do you think?

Regards,

Dan.

This is done with DISLIN library (http://www.mps.mpg.de/dislin/).
The frontend could be anything...

Sincerely,

Dmitri.

You can get a cheap version of this with the label_contours.awk
script from the gnuplot home page.

Personally, I like the following representation:

f(x,y) = sin(sqrt(x*x+y*y)) / sqrt(x*x+y*y)
Dcnt = 0.2
set samples 200
set isosamples 200
unset surface
set contour base
set cntrparam levels incremental -1, Dcnt, 1
set table "tmp.dat"
splot f(x,y)
unset table
unset contour

set size ratio -1
set cbrange [-1:1]
set palette defined (-1 'red', 0 'white', 1 'blue')
plot [-10:10] [-10:10] '++' using 1:2:(Dcnt*floor(f($1,$2)/Dcnt)) with
image, \
     "tmp.dat" w l lt -1
