Updated: gnuplot-4.2.4-1 - A command-line driven interactive function plotting utility.

["Dr. Volker Zell" <dr dot volker dot zell at oracle dot com>]

Hi

A new version of 'gnuplot' has been uploaded to a server near you.


DESCRIPTION:
============
Gnuplot is a command-line driven interactive function plotting utility
for UNIX, MSDOS, VMS, and many other platforms.  The software is copyrighted
but freely distributed (i.e., you don't have to pay for it).  It was
originally intended as graphical program which would allow scientists
and students to visualize mathematical functions and data.  Gnuplot
supports many different types of terminals, plotters, and printers
(including many color devices, and pseudo-devices like LaTeX) and is
easily extensible to include new devices.
Gnuplot handles both curves (2 dimensions) and surfaces (3
dimensions). Surfaces can be plotted as a mesh fitting the specified
function, floating in the 3-d coordinate space, or as a contour plot
on the x-y plane. For 2-d plots, there are also many plot styles,
including lines, points, lines with points, error bars, and impulses
(crude bar graphs). Graphs may be labeled with arbitrary labels and
arrows, axes labels, a title, date and time, and a key.  The interface
includes command-line editing and history on most platforms.

* NEW allow contouring of pm3d surfaces
* NEW allow color by z value ("palette z") in 2D plots
* NEW "pause mouse close" waits until the plot window is closed
* FIX Do not re-quantize time tics interval explicitly set by user
* FIX (gd post) don't segfault on very long font names
* FIX allow variable color from input file for "with boxes", "with vectors"
* FIX don't run off the end of "set format" commands
* FIX Fix discontinuity in piecewise approximation of inverse error function
* FIX discard out of range vectors in the bitmap terminals (pbm, epson, etc)
* FIX 2nd colour in the colour box for negative palette in postscript
* FIX insure palette is initialized before any objects are drawn
* FIX wxt terminal was not obeying "set palette maxcolors"
* FIX Histograms did not correctly honor 'set style user increment'
* FIX Avoid segfault if tic labels are requested from a non-existent data column
* FIX emf terminal - allow fractional linewidth (fixes 0-length dash problem)
* FIX post terminal - fix parsing error for palfuncparam
* FIX post terminal - escape {} chars in enhanced text mode
* FIX clip "splot with labels" against plot boundaries in 2D mode
* CHANGE try harder to autotitle columns in using specs with expressions
* CHANGE gd.trm: use dynamically-allocated TTF font names
* CHANGE x11: more finely sampled color palette for PM3D
* CHANGE cgm: switch to using web_color_rgbs; approximate RGB colors
* CHANGE fig: more point types, 4.2-style font and size syntax for "set term"
* CHANGE emf: separate dashlength option (don't use linewidth for dashlength)
* CHANGE stacked histograms grow upward for values > 0, downward for values < 0
* CHANGE 'pause mouse button1' (or button2) does not disable zooming
* CHANGE built-in readline tries to recognize <home> and <end> keys
