Certified Scientific Software's UNIX-based C-PLOT serves a wide range
of laboratory data handling needs, from quick plots of raw data,
through analysis and fitting, to generation of publication-ready
plots.
Currently installed at major university, industrial and national phy-
sics laboratories, C-PLOT is an affordable, time-saving way to bring
the power of UNIX to bear on your data analysis and presentation
needs. The software is flexible enough to accommodate both sophisti-
cated programmers and relative computer novices.
C-PLOT's features include:
* Publication-quality plots on HP-GL pen plotters and laser
printers. With its large library of ready-made filters, C-PLOT
supports most popular dot-matrix printers, graphics terminals and
other graphics devices.
* Interactive use or batch mode. Command files for batch operation
allow variable argument substitution and can be created with any
UNIX text editor.
* Multiple and inset plots with variable plotting window size.
* Greek, math and foreign characters, superscript and subscript in
8 fonts. Control height, width, tilt and rotation of text in all
fonts.
* On-line help files.
* Plot an unlimited number of points.
* Data entry from ASCII files or from the keyboard. C-PLOT will
digitize data from any HP-GL plotter or it can receive data
through its user function facility.
* Runs well on small or large computers.
C-PLOT's commands are simple one- or two-letter mnemonics. Users can
generate plots with as few as two commands, or they can use the
program's data analysis, plot design and text-formatting facilities to
tailor data presentation to the most complex specifications. Experi-
enced users can enter command qualifiers on the same line as the com-
mand, otherwise C-PLOT will list options and prompt for the needed
parameters.
C-PLOT's graphic data editor, suited to most video terminals, lets
users insert, modify and delete points as they are displayed on a
low-resolution plot. C-PLOT's text formatting procedures share many of
the control sequences of troff, the standard UNIX text formatter. The
size and position of text can be changed with simple commands.
Among C-PLOT's powerful data analysis capabilities are a number of
built-in functions and tools for creating user-defined functions.
These include:
* Nonlinear least squares fitting to your model (using the Mar-
quardt algorithm).
* Fast Fourier transforms.
* Cubic spline interpolator.
* Histogram maker.
* Data calculator.
* A bridge to UNIX shell commands.
* A user function facility that lets you create your own data col-
lecting and processing routines and integrate them with C-PLOT.
C-PLOT will automatically create files containing prototype sub-
routines; after you add your code, it will compile, link and run
the functions.
The C-PLOT package includes a 100-page manual and is available immedi-
ately for many UNIX systems (call for those not listed), including:
* VENIX on IBM XT/AT and compatible computers, with support for
CGA, EGA and Hercules graphics
* VENIX on DEC PDP 11 and DEC PRO computers,
* DEC ULTRIX and Berkeley 4.2/4.3 UNIX on all VAX and MicroVax sys-
tems and
* UNIX on Sun computers.
Prices start at $500.
