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.
