- is now gnuplot.exe.

-
- 1) Introduction
- ===============
-
- This file discusses the version of Gnuplot 3.5 implemented for OS/2 2.x.
-
- Version 3.5 is a minor revision fixing some bugs in 3.4.
- In the PM driver, some printing bugs have been fixed. Plotting
- should also be a bit quicker (plotting now starts when commands
- are received from gnuplot, rather than when the command list has been
- built).
-
- The command line interface of Gnuplot is retained, while graphics output is
- plotted in a Presentation Manager Window. The Gnuplot command line
- appears in another 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 colour, as dot/dashed lines, or both).
-
- The command line window offers the usual Gnuplot interface. Both Unix-style
- and DOS-style editing keys are supported.
-
- The Gnuplot program was compiled with the emx version of the GNU compiler.
- It supports the shell command (type 'exit' to return to Gnuplot), can pipe
- datafiles through external commands using '<', and supports command-line
- substitution. It runs the full set of demonstration programs supplied in
- the Gnuplot source code distribution without problems.
-
-
- 2) Running Gnuplot
- ==================
-
- Gnuplot can be run from the command line of an OS/2 session (preferrably
- 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 entered.
-
- 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 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 maximised: 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.
-
- 3) gnupmdrv.exe
- ===============
-
- Gnupmdrv.exe is the 'outboard' driver for Gnuplot. It is a multithreaded
- PM program.
-
- 4) Problems, etc.
- =================
-
- Gnuplot.inf has been generated by a translation program and may contain
- many inconsistencies.
-
- The 'Thick line' option may not be available with all screen drivers.
- It doesn't seem to be supported by the et4000 1024x768 driver that
- I use, for instance.
