NOTES TO PACKAGERS AND TESTERS
===============================
Configuration options for interactive use
-----------------------------------------
The 4.6 source code supports three primary cross-platform output modes
in addition to several platform-specific modes.
1) Cairo/pango/wxWidgets
These terminals were introduced in version 4.4 and are now the most
stable and full-featured option. This set of terminals includes
- pngcairo, pdfcairo, epscairo, and cairolatex for output to a file
- wxt for interactive display
This is the default configuration, but requires prior installation of
libcairo, libpango, libcairo, libwxgtk, and related support libraries
To disable these terminals:
./configure --disable-wxt --without-cairo
2) Qt
The new qt terminal supports interactive display with menu-driven
output to png, svg or pdf.
Requires libqt version >= 4.5
./configure --enable-qt
3) X11 (the "classic" interactive interface)
This used to be the preferred interactive interface, but the newer
wxt and qt terminals offer nicer output and a wider range of features.
Options for output to files
---------------------------
Of course the terminals (output modes) present in previous gnuplot versions
are also still available. These include, among many more obscure options:
- png/jpeg/gif output via libgd
- PostScript
- Many flavors of TeX/LaTeX output, including TikZ and ConTeXt (new)
- Bitmapped output to support many older devices (e.g. HP deskjet, epson,
seiko printers, pbm bitmapped graphics files) is available if needed
but is no longer configured in by default.
./configure --with-bitmap-terminals
Options for generating interactive plots for web display
--------------------------------------------------------
- Mouseable output for display on the web can be created using either
the canvas terminal (HTML5 2D canvas element) or the svg terminal.
Both allow zooming, toggling plot elements on/off, and user-scriptable
hot keys.
Online demo plots

OTHER NOTES
===============================
Installation
------------
You can download a source tarball for gnuplot version 4.6.5 from the
gnuplot development site on SourceForge.
http://sourceforge.net/project/showfiles.php?group_id=2055
Installation instructions are available in the source itself; the short
version for linux/unix-like systems is to unpack the tarball and then
build it:
cd gnuplot-4.6.5 ; ./configure ; make
test it:
make check
install it:
make install
Pay careful attention to the output of the ./configure script.
It may indicate that some output drivers have been omitted because the
necessary support libraries were not found. In general you need to have
previously installed the "*-devel-*" versions of these libraries.
Known issues
------------
- Mac OSX ships with a terminal input library that appears to be GNU
libreadline, but isn't really. The program tries to cope with this, but
you may get better results by configuring gnuplot to use either its own
built-in readline routines or the real GNU libreadline.
- The gnuplot build system is not very good at figuring out where to find
or install LaTeX-related files. This can affect use of the new lua/tikz
and ConTeXt terminals.
- You can configure support for both wxt and qt into the same gnuplot
executable, but only one of these two output modes can be used in any
given gnuplot session.
Support
-------
Please report all bugs and installation problems to the bug tracker
on SourceForge:
http://sourceforge.net/tracker/?group_id=2055&atid=102055
There is also an gnuplot discussion forum on usenet group
comp.graphics.apps.gnuplot
Development
-----------
Gnuplot development is quite active. The development branch on SourceForge
contains many new features. The current development branch is labeled
version 4.7, but will probably be released as version 5.
Feedback and contributions of code are very welcome.
