Certified Scientific Software introduces Version 3.6 of C-PLOT,
its UNIX-based graphics and data analysis software for scientific
users. Among the features and improvements introduced with
Version 3.6:
* keep track of up to 64K points at all times on all systems.
A special mode allows plotting from a file an unlimited number of
points.
* in addition to the flexible axis formatting features from
previous releases, now label and number left and right y-axis
indpendently.
* assign pen up/down information to each point to draw
distinct curves from a single data set.
* make contour plots from not necessarily uniform data grids.
* plot on more graphics devices, including many 24-pin dot
matrix printers, the Apple ImageWriter printer and the DEC LN03
laser printer.
More than ever, C-PLOT is the smart, low-cost alternative to do-
it-yourself programming that takes too much time away from
productive research. Why should grad students and post docs
spend their time writing this software when it has already been
written by us?
C-PLOT is a highly responsive package that will accommodate both
sophisticated programmers and relative computer novices and is
already in use at major university, industrial and national
physics laboratories nationwide. Its standard features include:
* Publication-quality plots on HP-GL pen plotters and on
laser printers (including HP, Apple and Imagen). With its large
library of ready-made filters, C-PLOT supports most popular dot-
matrix printers (Epson, Okidata, DEC, IDS, Diablo, Toshiba, NEC
and others), graphics terminals (Tektronix 4010/4014/4025 and
many emulators) and numerous other graphics devices. The filters
are simple to modify for devices not already supported.
* A user-function facility that makes it easy to integrate
existing data collection and handling routines with C-PLOT.
* Built-in user functions including nonlinear least squares
fitting to your model (using the Marquardt algorithm), fast
Fourier transforms, a cubic spline interpolator, a histogram
maker, a data calculator and a bridge to UNIX shell commands.
* Command files for batch operation that allow variable
argument substitution and can be created with any UNIX text
editor.
* A familiar user interface based on UNIX conventions. User
functions and graphics filters are written in C, and C-PLOT's
text formatting procedures share many of the control sequences of
troff, the standard UNIX text formatter.
* Multiple and inset plots with variable plotting window
size.
* Eight fonts. Greek, math and foreign characters. Control
placement, height, width, tilt and rotation of text in all fonts.
* 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.
* A graphic data editor, suited to most video terminals, that
lets users insert, modify and delete points as they are displayed
on a low-resolution plot.
* A detailed manual and on-line help.
C-PLOT is currently installed on many UNIX systems, including:
* VAX and MicroVAX systems running DEC ULTRIX, 4.2 BSD or 4.3
BSD.
* Sun-3 and Sun-4 workstations running SunOS. Filters are
integrated with SunView Windows and "graficstool".
* IBM XT/AT and compatible computers running VENIX, XENIX and
Microport System V.
* Intel 386-based PCs running Interactive Systems PC/ix.
* AT&T 3B2 running AT&T System V.
* DEC PDP 11 and DEC PRO computers running VENIX.
* HP9000 running HP-UX with filters for StarBase graphics.
* MASSCOMP workstations running UNIX.
* Encore multiprocessor systems running UMAX.
We can prepare a release of C-PLOT for many other UNIX systems,
and we can arrange to custom-install the package by modem.
Prices start at $500 for the XT/AT version, $750 for MicroVAX and
Sun 3.
