Advice on Technical Plotting Software for DECstation Wanted

[Charlie Li]

Hi,

We need to draw 2D and 3D graphs on Decstation 5000 running Ultrix with 
DecWindows, Tektronix terminals and HP LaserJet/Apple LaserWriter printers.
IMSL has a package Exponent Graphics for this, but quite expensive ($1575).
Anybody has experince with it?  Is it good? Compare to IGL/AGII.  Is there
any similar technical plotting library or fully menu driven package with
good price or in public domain?  I attach some information of IMSL's
Exponent Graphics to this mail for reference.

Thank you for your advice in advance.  Sorry if I post to a wrong group.

IMSL gives 2D and 3D Technical Plotting a new soltuion: Exponent Graphics
It uses over 70 FORTRAN callable subroutines to make following plots:

Scatter plots (2D & 3D)          Bar charts (2D & 3D)
Function plots (2D & 3D)         Polar plots
Splines                          Pie charts
Contour plots (2D & 3D)          Filled area charts
Box plots                        Error bars
Vector plots (2D & 3D)           Confidence interval
Historams (2D & 3D)

Machines supported: DECstation running Ultrix RISC FORTRAN, Sun
                    Sparcstations running SunOS, HP and many other platforms.
