- Announcing ACE/gr Release 3.00 (patch level 0)
-
- I wish to thank all who have participated in the development of
- ACE/gr.
-
- ACE/gr (AKA xmgr) is an XY-plotting tool for UNIX workstations using
- X/Motif. ACE/gr is an unfunded, unsupported, after-hours project that
- I hope proves useful.
-
- A current version of the source, documentation, and some examples are
- available via anonymous ftp to:
-
- ftp.ccalmr.ogi.edu [129.95.72.34]:CCALMR/pub/acegr/xmgr-3.00.tar.Z
-
- Remember to use a binary file transfer.
-
- There are compiled binaries (without support for NetCDF/HDF) for several
- architectures in:
-
- CCALMR/pub/acegr/bin
-
- xmgr.HPUX9.bin.Z ... HP PA-RISC HPUX 9.x X11R5/Motif 1.2
- xmgr.IRIX5.bin.Z ... SGI IRIX 5.2 X11R5/Motif 1.2
- xmgr.RS6K325.bin.Z ... IBM RS6K AIX 3.2.5 X11R5/Motif 1.2
- xmgr.LINUX.bin.Z ... LINUX Slackware 1.0 X11R5/Motif 1.2
- xmgr.ULTRIX42A.bin.Z ... DEC MIPS Ultrix 4.2a X11R5/Motif 1.2
- xmgr.SUN413.bin.Z ... SUN SunOS 4.1.3 X11R5/Motif 1.2
- Will not work on Solaris 2.x
-
- I could use a Solaris 2.x binary (bind it statically). Disk space
- is at a premium around here, so I don't know how long these binaries
- will be available (at least a week or so).
-
- I am not able to E-mail ACE/gr, but there are services provided by various
- Internet sites that allow ftp by mail. You might try sending mail to
- ftpmail@decwrl.dec.com as follows:
-
- Subject: (hit return) Body-of-letter: help (return) quit
-
- I've not tried this, but it should give you instructions on how to use
- this service.
-
- There is now a mailing list for users of ACE/gr send mail to:
-
- majordomo@admin.ogi.edu
-
- with a body of (not in the "Subject:" line):
-
- subscribe acegr
-
- to subscribe. Majordomo is a mail list management package, and automatically
- handles additions and removals from the list. For information about majordomo
- at our site, sent mail to majordomo@admin.ogi.edu with a body of
-
- help
-
- Please use the mailing list for comments, suggestions, help, and
- bug reports. Unlike my previous attempt at a mailing list, this
- (theoretically) requires no effort on my part to maintain it.
- To send mail to the list, use acegr@admin.ogi.edu.
-
- The mail list should provide better service and less duplication
- of effort. Furthermore, to receive any response from me regarding
- problems with ACE/gr, you must be subscribed to the mail list.
-
- About ACE/gr:
-
- * Point&click Motif interface.
- * 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. There is no longer any limit on
- the number of graphs or sets, the default is 10 & 30.
- * Data read from files and/or pipes.
- * Support for reading 1 dimensional variables from NetCDF files.
- Using NCSA's NetCDF/HDF, 1 dimensional variables can be read
- from SDS.
- * 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.

- Please send comments, suggestions, bug reports to acegr@admin.ogi.edu.
