Try this, I sure like it: |From: pturner@ogccse.ogc.edu (Paul Turner) |Subject: Announcing grtool - a data/function plotter for Sun's under 4.0+ |Date: 16 Sep 89 06:03:31 GMT | |Announcing the availability of grtool, a data/function plotting program |for Sun's running SunOS 4.0. I'm calling this release a Beta test. | |Features: | | o Linear and polynomial regression | o Running averages | o Histograms | o Numerical integration and differentiation | o Fourier spectrum (DFT by FFT or by definition) | o Auto and cross correlation | o Transformations *,/,-,+,^, +built in functions & constants | (using this and linear regression gives exponential and power | fits). Uses a yacc grammer. Like y=(x+1)*cos(2*PI*x/10)+1 | o Labels (x-axis, y-axis, title, subtitle) | o Legends - placed anywhere on plot | o Strings, rotated, sized (but not typed on the canvas). | Subscripts, superscripts, and special symbols (I used | the Hershey fonts). | o Boxes and lines | o Parameter files for saving a given plot setup | o Batch mode for unattended plots | o 15 sets, size limited by memory - easy to add more, | 15 is about all I've ever needed. | o Linear, log-linear, linear-log, log-log plots | o Many symbols, grid lines, spikes for spectral plots | Sets can have both symbols and linestyles. | o Linestyles, and thickness (in lieu of color). | o Adjustable tick mark density, inward or outward pointing. | o Autoscale | o Flip x <-> y | o Locate, delete individual points | o Set world and viewport | o Pan and zoom | o Can use mouse to set viewport | o Locator (reports mouse position in world coordinates) | o Reads ASCII data - X Y 1 point per line, | X Y1 Y2 ..., and from pipes. | o reports Mean, std. dev., min, max of each set | o Error bars, equal or unequal, one or two sided, along X or Y | (max 7 sets with error bars). | |Hardcopy support is HPGL and PostScript. There is a hack for HP laserjets |using rasterfiles. Grtool is quite capable of producing (and has produced |many) publication quality graphs (which isn't saying much, I know). | |Thanx to Jim Hudgens for the PostScript driver. | |In all modesty, I believe grtool to be nearly as functional as TempleGraph |and with the inclusion of source code perhaps more so. Grtool has a distinct |price advantage. | |Grtool may be acquired via anonymous ftp from cse.ogc.edu [129.95.40.2] in |pub/grtool/grtool.tar.Z (set type binary). If you don't have Internet |access I'd be happy to send a shar archive, tapes for hardship cases only |please. | |I call this version V1.0 Beta test, it will not run under SunOS 3.5 or less. |Comments regarding this program would be appreciated. | |Paul J.
