Announcing xvgr Release 2.09

I wish to thank all who have participated in the development of
xvgr.

xvgr is an XY-plotting tool for SUN workstations using
X or OpenWindows.  There is a Motif version called xmgr for
everyone else. Collectively, these 2 tools are known as ACE/gr.
Compilation of xvgr requires the XView toolkit.

The Motif version is in the shop but should be ready to
go shortly.

2.09 is a bug fixer and has removed from it any reference to the notion
that I'll be able to respond to every email message sent to me. Time
constraints prevent me from making individual answers. Also, any references
to a mailing list in previous versions have been removed - again,
time constraints make it impossible for me to maintain any sort of
mailing list. I would suggest that the users of xvgr get together
and form either a traditional mailing list, or use an existing
news group for the discussion of bugs, comments, complaints, etc.
Comp.sys.sun.apps would probably be an appropriate news group for
xvgr, or maybe comp.windows.x.apps as this would cover both versions.
I'm inclined to answer questions in some forum that has a larger
audience.

If you are using any version of xvgr less than 2.04, you should
consider upgrading.

A current version of the source, documentation, a compiled binary
for Sun SPARC, and some examples are available via anonymous ftp
to amb4.ese.ogi.edu [129.95.20.76] in CCALMR/pub/acegr/xvgr-2.09.tar.Z.
Remember to use a binary file transfer. I am not able to E-mail xvgr,
but there are services provided by various Internet sites that allow
ftp by mail. You might try sending mail to [e-mail]
as follows:

I've not tried this, but it should give you instructions on how to use
this service.

Xvgr is an unfunded, unsupported, after-hours project that I hope proves
useful.

A few of its features are:

   * Motif and XView versions.
   * Plots up to 10 graphs with 30 data sets per graph.
    each data set is limited by the size of available memory,
    I've plotted data sets in excess of 700k points.
    The 10 graphs may be displayed simultaneously with
    a popup that allows the graphs to be conveniently stacked,
    in rows and/or columns.
   * Data read from files and/or pipes.
   * Graph types XY, log-linear, linear-log, log-log, bar,
    stacked bar charts.
   * Sets may be drawn with error bars in both directions equal or unequal
    on either side of the datum in X and in Y. Support for HI LOW OPEN
    CLOSE data, Numerous symbol types, both hollow and filled, skyline
    plots, histograms, impulse. Sets may be draw as polygons filled
    in several different ways, from the data to the graph minimum Y,
    maximum Y, minumum X, maximum X, X = 0.0, Y = 0.0, or as a polygon.
   * Block data feature for those data sets arranged in equal length
    columns allowing sets of any type to be formed by any combination
    of the columns. Presently there is a 30 column limit, the length
    of the columns is limited by available memory.
   * Continuous display of the location of the pointer depending on
    the current graph scaling. The format of the display can be
    set to any of the time-date formats, latitude/longitude. The
    default is to display the XY coordinates of the mouse in user
    coordinates. As the graph focus changes, so does the format
    and scaling of the locator.
   * User-defined scaling, tick marks, labels, symbols, line styles,
    colors. Tick labels may be drawn at any angle on either
    or both sides of the graph, staggered (offset for long
    labels). There are several formats for tick labels, including
    many time-date formats, latitude-longitude, decimal, exponential
    and power-of-10. Tick labels and tick marks may be specified
    by the user. Grid lines may be drawn in lieu of tickmarks.
    Each coordinate direction allows 3 axes, the primary, zero,
    and an alternate axis that allows a scale differing from the
    graph coordinate scaling.
   * Graph legends.
   * Annotative text with sub/super scripts, lines with/without arrow heads,
    boxes filled or unfilled.
   * Operations on data sets, kill, copy, move, reverse, sort, drop,
    join, coalesce, write, swap.
   * Region operations, define a region as inside or outside a polygon,
    or half planes defined by a line. Extract points from a region
    to a set, delete points, evaluate an expression on points in a
    region. Area and perimeter calculations from a polygon.
   * Mouse powered point editing, add points to a set, delete points
    from a set, move a point in a set (horizontally, vertically,
    or in both directions). There is a feature called tracker that
    when active, warps the pointer forward or backward through the
    points in a set, displaying the set number, the index of the point,
    and the X, Y location of the point. There is a find point feature
    that allows information to be displayed about arbitrary points
    in sets.
   * Batch mode for unattended plotting.
   * Read and write parameters used during a session.
   * Polynomial regression, splines, running averages/minimums/maximums/
    standard deviations/medians, DFT/FFT, spectrum, phase, sampling,
    cross/auto-correlation, numerical integration, numerical
    differentiation, histograms, evaluate expressions on sets.
   * Pan, zoom (mouse powered), shrink and expand the graph scaling,
    with each graph allowing 20 different views through a mechanism
    called the world stack. The graph viewport (where it appears
    on the page) can be set manually or by the mouse.
   * Command line interpreter with a history list and playback feature.
   * Autoscaling along each or both coordinate directions, on all sets
    or a selected set.
   * Support through device independent graphic drivers for
    PostScript, HPGL, and FrameMaker .mif format.

Comments, suggestions, bug reports to [e-mail] (if mail
fails, try [e-mail]). Due to time constraints, replies will
be few and far between except for suggestions on how to get me out from
under all this e-mail - messages on this topic will be answered promptly.
