I've made some progress with xvgr and the result is available
via anonymous ftp to ese3.ese.ogi.edu [129.95.20.62] in 
pub/grtool/xvgr-1.06alpha.tar.Z, be sure to set transfer type to 
binary.  I thank all who have contributed comments, suggestions, and 
bug reports, and I hope people will continue to provide the necessary 
feedback that will make xvgr a useful and reliable tool. 

About xvgr:

Xvgr is the XView version of the SunView based plotting tool called grtool.
I have successfully compiled and executed it on Suns, and a Sequent Symmetry 
all running X11R4. I have had reports of success on DEC 3100s. It should port 
easily to BSD based systems (given XView). This release is primarily a 
bug-fixer.

Features are:

   o  15 data sets per graph and 11 graphs per page.
   o  Support for color servers
   o  Set size limited by memory (my personal record is app. 467,000 points)
   o  hardcopy output to PostScript, HPGL - spooled or written to a file.
   o  Linestyles, linewidths, colors, and numerous symbols.
   o  Annotative text (any angle), lines (with arrowheads), and boxes.
   o  Adjustable tickmarks and tickmark labels.
   o  Legends.
   o  Log plots.
   o  Error bars (in X and Y, left/top right/bottom or both).
   o  Mouse powered point locator, distance, area, and perimeter computation.
   o  Find, add, delete points in a data set with mouse.
   o  Pan and zoom, autoscaling.
   o  Data read from files, pipes, or stdin.
   o  Parameter files.
   o  Linear/polynomial regression.
   o  Expressions - math on data sets (with some effort, between sets).
   o  Splines, running averages/medians/extrema/standard deviations, 
      DFT/FFT, cross/auto-correlation, point sampling, parametric functions,
      histograms, numerical integration/differentiation, linear convolution.

Coming attractions:

 o  I should have a prototype Motif version within a month or so.
 o  grtool/xvgr has accumulated so many warts in the past year that 
    I'm re-writing it from the ground up. I promise to fix the log-plot 
    botch. If you have enhancement requests, you might pass them along.
    I have purchased both style guides for OL and Motif and will make
    every attempt to produce a conforming interface.
