Xmgr list of changes


From 3.01 to 4.00alpha:

* added a new demo, cd to examples and run: xmgr -arrange 2 2 -b test.com * No limit on the number of columns of block data. See the -maxblock option. * Added formats YYMMDD and YYMMDDHMS For tick labeling. * Colors can be changed on the fly. * Tick marks and grid lines are now set separately. * Added as274 for performing the least squares fits for polynomials, seems to be fairly robust, the default is the original - form the normal equations and use gauss elimination. * Allow logging of strings passed to the scanner, should help in debugging batch files. * Tick marks and gridlines are now drawn separately - you can have ticks OUT while having gridlines. * Edit points has been rearranged, the popup for the location and the buttons for actions are now in the same popup. * Added a command (LENGTH) that can be used to either truncate or lengthen a set. * Added commands to kill sets, but save the parameter settings (KILL <SETNUM> SAVEALL) * Added ARRANGE command, this does not allow the control over the layout that the popup does, but should be useful.

From 4.00alpha to now:

Patch level 0

* [ES] fixed problems with XBAE cell editing * [ES] fix to make multiple selection and "Select all" work in `Data/Transformation/Geometric' * [ES] in the `Geometric' transformation, direction of X & Y translations was wrong * [ES] F* keys work for Linux * [ES] no segfaults in 16 bpp mode * [PN] pen patterns for framemaker (mif) works correctly * [EV] computation of bounding box for eps * [EV] use of left and right arrow keys in text edit mode * [EV] editing of sets with text editor (Edit/Create Set) when XBAE not present * [EV] implementation of backspace for Postscript * [EV] cursor must be close to picked objects, eliminates "must kill" mode * [EV] implementation of annotative ellipses * [EV] improved editing of objects * [EV] proper moving of filled objects * [EV] postscript now fills with patterns * [PN] when editing text, the following keys are available: ^a - go to beginning ^e - go to end ^k - delete to end ^u - delete to start * [ES] fix for the power regression (y = a*x^b) * [ES] when compiled with XBAE, creating a new set is possible (with $GR_EDITOR, or vi as a default) * [ES] `examples' directory cleaning * [ES] extracting OS-specific or otherwise configurable parameters from Makefile into Make.arch and Make.conf respectively * [EV] text string editing * [EV] code to distinguish between postscript level 1 and 2 printers and alter pattern fill accordingly * [EV] fix for bounding box for eps files that was sometimes computed incorrectly * [ES] some minor code & documentation fixes and rearrangements * [ES] adding a primitive `configure' script

Patch level 1

* [ES] code fixes and rearrangements (still far from being complete) * [ES] building a non-GUI version works out of the box now * [ES] new functions added to the parser: hyperbolic (sinh, cosh, tanh) and inverse hyperbolic (asinh, acosh, atanh). This was suggested by Jens Schneider <jschneid@gluon.physik.uni-kl.de> * [ES] tick marks & labels didn't show up in the zero X/Y axes if the axes didn't contain 0. (pointed out by James J. Szydlik <szydlik@cgrer.uiowa.edu>). Fixed

Patch level 2

* [JK] fix for loop when processing a read command from command interpreter * [ES] on-line & context-sensitive help facility added, but by now, it is enabled only for a small part of widgets * [ES] GR_HELPVIEWER is now in the printf(3) format, with %s being replaced by a help URL anchor. The default GR_HELPVIEWER string is now "netscape -raise -remote openURL(%s) >/dev/null 2>&1 || netscape %s". This will try to connect to an already running netscape, and if fails, silently run a new one * [ES] added support for libhelp (tested with ver. 1.8.1) - a light-weight hypertext help system of Thomas Harrer. If this is enabled, GR_HELPVIEWER will be ignored. See Make.conf for more details * [ES] documentation a bit updated * [ES] in the print setup, option to disable PS Level 2 features. Should eliminate problems some people encountered with old printers * [EV] Xbae cell editing fixes * [EV] added interpolation: create a new set by performing interpolation on one set at abscissas from another set. Can be done by linear, cubic spline or Akima spline (see below) approximation * [EV] in "Edit/Create set", option to define new set by a formula * [ES] fixes for custom positioning of axis labels: both dx and dy work and are updated under axis flip/invert correctly * [ES] menus rearranged * [ES] Akima splines added. Nice when approximating essentially non-smooth series. The code is taken from David Frey's Spline-1.0 package and modified to suite xmgr * [EV] option to strip absolute path from legend strings when data is read from a file * [EV] if reading data from file a, the first column of data is commented a:1 and the next a:2, etc * [EV] when printing to a file, default filename is the project name + type-specific extension; file selection widget added * [ES] new functions in parser: interpolation: INTERP (SET1, SET2, method), where the method could be either 0 (linear), 1 (cubic spline) or 2 (Akima spline) Akima spline: ASPLINE(SET, START, STOP, NPOINTS) * [EV] fix for string edit popup - the rotation angle was not updated * [EV] fix for the U umlaut - \c\\ should work as expected

Patch level 3

* [ES] non-linear fit rewritten * [ES] misc bug fixes * [ES] "File/Open" automatically distinguish between type of project (binary/ ascii). "File/Save" has option to choose the type * [RN] VMS port; some code fixes * [EV] project description (binary format only) * [EV] added project name to footer string * [EV] verify overwrite on "File/Save" * [EV] "All line styles" and "B/W" options in "Plot/Symbols" * [SB] reducing size of PostScript files by inserting symbol definitions; some code fixes * [EV] Graph arrange enchancements * [ES] New symbol types: "Location X", "Location Y", and "Location (X,Y)"; the former "Loc" renamed to "Index" * [ES] Switch to pulldown/pullright menus * [ES] Ultrix port Legend: [EV] - Ed Vigmond <ed@gut.rose.utoronto.ca> [PN] - Per Nordlund <pern@hallf.kth.se> [JK] - James Kingdon <jbk@pac.soton.ac.uk> [RN] - Rolf Niepraschk <niepraschk@ChbRB.berlin.ptb.de> [SB] - Scott Berg <Scott.Berg@cern.ch> [ES] - Evgeny Stambulchik <fnevgeny@plasma-gate.weizmann.ac.il>
