Version 5.4.2 introduced major changes to the OS/2 version, see below. Please give this release some testing. Bugs should preferrably be reported using the SourceForge bug tracker at https://sourceforge.net/p/gnuplot/bugs/ This binary was compiled using Eberhard Mattes' EMX 0.9d fix 04 and Andrew Zabolotny's port of gcc 3.2.1. (Support for gcc 9 and kLIBC is being worked on.) The binary includes most relevant terminals. It was compiled with gdlib 2.2.5, libpng 1.6.28, zlib 1.2.11, libjpeg 6b, and freetype 2.9.1. It includes support for iconv using Ilya Zakharevich's iconv2 library 0.2.1a, and for lua using version 5.1.5. For general NEWS on this release, see the corresponding file. Here we list some changes *specific* to the OS/2 version and the pm terminal: Upcoming changes CHANGE variable line width always enabled Version 5.5 (upcoming changes in next major version) NEW support mouse input anytime: during "pause", "load" and "pause mouse" NEW bilevel transparency for RGBA images NEW support "toggling" plots by mouse, key, or command NEW link with AMOS and libcerf libraries CHANGE true bold and italic fonts CHANGE compilation with gcc 9 using kLIBC CHANGE activate mouse by default as on other platforms CHANGE status bar to diplay status text CHANGE use the standard font dialog (again) to select fonts Version 5.4.3 No changes specific to the OS/2 version. Version 5.4.2 NEW new terminal options linewidth, pointsize, and fontscale NEW draw RGBA images disregarding the alpha channel NEW draw coordinates during zooming with mouse NEW line-to-ruler feature NEW Unicode escape sequences when using utf8 encoding NEW support 64bit integers NEW raise graph window on mouse click CHANGE cosmetic changes to dialogs CHANGE colors are mapped to gray when color mode is deselected CHANGE revised gnupmdrv help CHANGE new parser for terminal options FIX fix long-standing bug which prevented drawing of "large" images, e.g. RGB exceeding ~200x200 pixels FIX many fixes to font selection FIX pause command listens to stdin if gnuplot input is redirected FIX prevent segfault when resizing or moving other windows over gnupmdrv FIX fix ancient bug in IPC which lead to missed characters on the command line FIX a few more fixes to wide line support FIX pass current character size information to gnuplot core Version 5.2.7 NEW (simulated) bold and italic text NEW extended support for encodings, including UTF-8 NEW dashtype support NEW default font terminal option CHANGE apply fill style to polygons CHANGE apply RGB colors to filled boxes FIX ignore alpha component of RGBA colors FIX many fixes to wide line support FIX several mouse and menu related fixes Known pm terminal bugs or limitations in 5.4: "pause mouse" and "pause mouse key" have not yet been implemented. "Mousing" is not enabled during "pause" (unlike on other platforms). Toggling plots by mouse or by the toggle command is not available. These issues have been fixed in the 5.5 branch already. In contrast to older releases, "wide lines" in 5.4 really enables changeable line thickness. In 5.5 (and maybe 5.4.4), variable line width will always be enabled and the meaning of the "wide" option will match the documentation again. "pause" cannot be (reliably) interrupted with Ctrl-C. Out of memory when running hidden_compare.dem gnuplot won't recover if gnupmdrv is closed e.g. due to a crash. terminal options override GUI settings and changes there (wide, font), in particular also the one saved to the profile. There is no support for boxed text, nor hypertext. No custom dash patterns, and dash patterns do not scale with linewidth. No transparency / alpha channel support. Other known limitations: Limited special function support (no libcerf) libgd is not linked with fontconfig and hence has no support for looking up fonts by name. cairo terminals (pngcairo, pdfcairo, webp), and the qt terminal are unavailable with EMX. 1) Introduction =============== gnuplot offers a command line interface of and graphics output is displayed in a Presentation Manager or X11 window. The gnuplot command line appears in a text-mode window on the screen. The PM window has facilities for printing the plot on the default printer, for changing the fonts used on the plot, and for switching between different ways of plotting the lines (with color, "wide" lines). Multiple graph windows are supported, see "help term pm". The command line window offers the usual gnuplot interface. Both Unix-style and DOS-style editing keys are supported. This build supports the shell command (type 'exit' to return to gnuplot), can pipe data from external commands using '<', and supports command-line substitution. It runs the full set of demonstration programs supplied in the gnuplot source code distribution. (With the exception of the currently unsupported special function demos and an out-of-memory condition in hidden-compare.dem.) In comparison to version 4.6, the pm driver was improved to support polygon filling with patterns, dashed lines, bold and italic text and more text encodings, including UTF-8 (see e.g. "utf8.dem"). A number of bugs concerning wide lines, images, filled boxes, alpha channel and the user interface have been fixed. Also the x11 driver was fixed. The documentation in gnuplot.inf was improved to include graphics. In version 5.4, the parser for terminal arguments was replaced. This also enables the `set termoption` command. The terminal now supports a "font" option to select a default font, as well as a few other new options. Mousing is enhanced to support drawing of zoom-coordinates and the line-to-ruler feature. In monochrome mode, colors are now mapped to gray. For news on general changes in versions 5.0, 5.2, and 5.4 see the RELEASE_NOTES, and NEWS files. 2) Installation =============== Most required DLLs are included in the package, but you still need the EMX libraries. Unzip the gnuplot distribution into a directory in the PATH, or unzip it somewhere and add this path to PATH, e.g. SET PATH=...;C:\Apps\gnuplot\bin gnuplot can be run from the command line of an OS/2 session (preferably a windowed command session, so that the command line and the displayed graph can be viewed at the same time), or can be set up as a program object in the WPS. The supplied makeobjects.cmd script will create two objects on the desktop for the program and the help book. If gnuplot is set up as a program object, it can be configured for 'drag and drop' in the usual way, by specifying '%*' as the program parameter. Environment settings: see manual (or 'help environment' in gnuplot) * PATH -- see above * SET GNUPLOT=<some directory> -- directory containing GNUPLOT.INI file, run at start-up. * SET GNUHELP=<path>\GNUPLOT.GIH -- path to gnuplot help file, if not in same directory as gnuplot.exe. * Variable GNUPLOT_LIB may be used to define additional search directories for data and command files. The variable may contain a single directory name, or a list of directories separated by a platform-specific path separator, i.e. ':' on Unix, or ';' on DOS/Windows/OS/2/Amiga platforms. The contents of GNUPLOT_LIB are appended to the `loadpath` variable, but not saved with the `save` and `save set` commands. See 'help loadpath' for more details. * Variable GDFONTPATH is the directory where the png/jpeg/gif terminals look for (TrueType or other) fonts. The included gd library uses a default of "C:\\PSFONTS" Usually, it is SET GDFONTPATH=C:/PSFONTS SET GDFONTPATH=C:/OS2/MDOS/WINOS2/SYSTEM The default font for of the gdlib based terminal can be changed via the environment variable GNUPLOT_DEFAULT_GDFONT; however, it is preferred to change the font via the "set terminal png font '<font>'" command. * The variable GNUPLOT_FONTPATH is used by the postscript driver as search path for fonts. Set it to SET GNUPLOT_FONTPATH=...as above... See also "help environment" and the supplied "startgp.cmd" script. 3) Running gnuplot ================== gnuplot can be run from the command line of an OS/2 session (preferably a windowed command session, so that the command line and the displayed graph can be viewed at the same time), or can be set up as a program object in the WPS. gnuplot starts up as a command line session which accepts the usual gnuplot input. The Presentation Manager window for graphics display is only opened when the first 'plot' or 'splot' command is executed. If gnuplot is set up as a program object, it can be configured for 'drag and drop' in the usual way, by specifying '%*' as the program parameter. The PM window has facilities for printing the plot, for changing the fonts used in the plot, and so on. These of course are handled through the usual PM interface. In addition, you can 'drop' a font onto the window to change the font. The PM terminal supports mousing and hotkeys (for very long time actually -- since 1998). The usual gnuplot commands can also be used to produce output on supported devices. Settings and the positions and sizes of the windows can be saved in the file gnupmdrv.ini. This file is saved in the program's working directory; several different directories can be set up (as program objects) with different options, if you wish. gnuplot can be run with the PM display window maximized: clicking on the 'gnuplot' menu item (or pressing 'ESC') will bring the gnuplot window to the foreground; it will disappear again when plotting begins. gnuplot itself communicates with the PM display window (which is a separate program) through a named pipe. Plotting commands are sent to the PM window which produces the plot when all commands have been received. 4) gnupmdrv.exe =============== gnupmdrv.exe is the 'outboard' driver for gnuplot. It is a multithreaded PM program. 5) X11 support ============== This version of gnuplot also includes the X terminal outboard driver gnuplot_x11.exe. It is compiled using the XFree86-OS/2 libraries and was tested using HOBlink/X11. 6) REXX support =============== gnuplot supports REXX: Any non-recognized command typed at the gnuplot command line is assumed to be a REXX command file. If the file exists it is executed, and all non-REXX commands are passed on to the gnuplot environment. (If the file does not exist, the usual error message is given). Files are searched for in the current directory, and then in the path. Note that Rexx maps all command strings to upper case, so gnuplot commands must be enclosed in quotes. Try 'testrexx' for a simple example. 7) Crash reporting ================== This release of the gnupmdrv supports extended crash reporting using the exceptq library if available. Please attach the trap file if reporting bugs via the SourceForge bug tracker. https://sourceforge.net/p/gnuplot/bugs/ 8) Contents =========== bin\: gnuplot.exe -- gnuplot executable gnupmdrv.exe -- Presentation Manager terminal driver gnuplot_x11.exe -- X11 driver gnuplot.ico -- OS/2 gnuplot icon gnuplot.gih -- gnuplot help file gnuplot.INF -- gnuplot manual in OS/2 inf format ('view gnuplot') gnupmdrv.HLP -- help file for gnupmdrv.exe gpsavediff.cmd -- script to cleanup output of the "save" command gpsavediff -- as above, but for bash startgp.cmd -- optional start-up script testrexx.cmd -- simple REXX example file share\PostScript -- prologue files for postscript output BUGS -- bug list from source distribution Copyright -- gnuplot copyright README -- README file from the source distribution RELEASE_NOTES -- notes from the source distribution README.OS2 -- this file demo\ -- demo files ('load "all.dem"') docs\ -- gnuplot manual in html and Postscript format contrib\ -- few contributed scripts etc. -------------------------------------------------------------------------------- The gnuplot team, January 2022
