fellow netlanders, i was wondering if anyone knows of a plotting program which allows the user, me folks, to pan through the data. in other words let us say one has lots of x data, but not much y data, and let us say that one does not want to scale all of the x data to fit on one screen (page), does a plotting package exist that will allow you to plot off-screen and then allow one to "pan" over the data? operating conditions: apollo dnxxxx's running sr10.2 Display Manager/GPR-based plotters preferred X11R3 also running, hence X-based plotters equally welcome could have access to SGI boxes if need be. p.s. is there anything in the NCSA suite of stuff that i should be aware of? thanks in advance apollo@ecf.utoronto.ca .vp

Here is an example of use. I am looking for an approximation of some data, the abscissas of the maximum of a function that Maple and Macsyma could not handle. ---------------------- % gnuplot > set samples 1000 > set dummy p > # "points.x" contains 980 points generated by a FORTRAN prog > # The x values range from 2 to 100 and the y values from 1 to 150 > plot [2:100] [0:200] "points.x" with lines, 2 * p + 3, 2 * p + 7 > # Print this on the laser printer > # load "qms" is a shorthand for: > set term postscript > set output '/tmp/gnuplot.ps' > replot > set output > set term apollo > ! prf /tmp/gnuplot.ps -d -transparent -pr qms800 ------------------ I got GNUPLOT v1.1 from a tape made at Carleton University in 1988 under AEGIS 9.7, but v2.0 is in labrea.stanford.edu: pub/gnu 292564 Apr 16 1990 gnuplot2.0.tar.Z But i dunno if this is working on an APOLLO at SR10.1. If you are using stats, there is also xlispstat working under X11. > Subject: Re: XLISP-STAT on APOLLOS? > Date: Mon, 21 May 90 > From: Luke Tierney <luke@umnstat.stat.UMN.EDU> > > no port to the native Apollo graphics system has been done.
