- A new version of xgraph is now available. Xgraph is a popular
- two-dimensional plotting program that accepts data in a form similar
- to the unix program graph and displays line graphs, scatter plots, or
- bar charts on an X11 display. These graphs are fully annotated with a
- title, axis numbering and labels, and a legend. Zooming in on regions
- of a graph is supported. The program can automatically generate
- hardcopy output to Postscript printers and HPGL plotters. A new
- option allows xgraph output to be directly pasted into idraw for
- further annotation.
- This program is NOT a widget. It is a stand-alone program written at
- the Xlib level and should run on any machine with a reasonable
- implementation of X11 release 3 or later. The source for the program
- is available through anonymous ftp to shambhala.Berkeley.EDU
- (128.32.132.54):
- % ftp shambhala.Berkeley.EDU
- Name: anonymous
- Password: <anything non-null>
- ftp> cd pub
- ftp> binary
- ftp> get xgraph-11.tar.Z
- ftp> quit
- % uncompress xgraph-11.tar.Z
- % tar xf xgraph-11.tar
- This will create a directory called xgraph-11. In that directory
- you will find a file called README.INSTALL that contains directions
- for building the program. I plan to submit the sources to the
- moderator of comp.sources.x after I have tested the program under X11
- release 4 (meaning a few weeks after the X Consortium releases the
- distribution).
- Those who do not have ftp access can obtain the source for xgraph
- using a mail archive system I have installed on dent.Berkeley.EDU
- (courtesy of Brian Reid at Digital). An example is given below:
- To: ucbvax!dent!archive-server
- Subject: send programs xgraph.shar.01 xgraph.shar.02
- send programs xgraph.shar.03 xgraph.shar.04 xgraph.shar.05
- send programs xgraph.shar.06 xgraph.shar.07 xgraph.shar.08
- The archive server will send you these files as time and load permits.
- They are standard shell archives and can be unpacked by running them
- through /bin/sh (in order). If you would like to know more about the
- mail server, send a message with a subject of "help". I am afraid I
- am no mail wizard so I cannot help you determine a path to dent.
- For those familar with xgraph, the most important changes are
- summarized below:
- - A new data reader has been written that allows discontinuous data in
- each data set. Also, nearly all of the display options for xgraph
- can be set in the data file. The reader is also more forgiving
- about blank lines and excess white space.
- - A new option has been added to the Postscript hardcopy facility to
- allow xgraph output to be included in other documents using psfig.
- As mentioned above, xgraph output can be imported into idraw for
- further annotation if necessary.
- - I received lots of complaints about the way xgraph obtains fonts and
- visuals. The new xgraph uses a much simpler scheme to obtain these
- resources and has fall back code to insure it will run in almost any
- situation.
- - Options handling has been cleaned up substantially. Xgraph options
- can now be specified as X resources (~/.Xdefaults), in the data
- file, or on the command line.
- - Drawing is somewhat faster on some servers due to a better choice of
- initial defaults.
- Please send all bug reports, questions, comments or suggestions to
- the electronic address below.
