This is version 1.1 of yplot, a Yorick (1.4) front-end to PLplot (5.0.4).
-------------------------------------------------------------
The detailed changes between versions are given in the CHANGES file that is
part of this distribution. Note especially where API changes are noted for
1.1.  yplot-1.1 is the first version of yplot to take advantage of PLplot-5
so there are extensive API additions compared to previous versions.  It only
works with version 5.0.4 of PLplot (released 2001 June 15) which finally
solved the portrait-mode bug that was holding up release of yplot.

What is yplot?
--------------
YPLOT is meant to be a useful tool in creating scientific plots of both
draft and publication quality quickly and efficiently.

YPLOT can do the following in the hands of even an inexperienced user:
o Access to all the capabilities of Yorick. Do all your data generation,
  interpretation and plotting from one package.
o Linear plots
o Log-log plots, with any variations of log and linear axes possible
o 3D surface and mesh plots (there is a difference, really ;-)
o 3D line and scatter
o 3D shaded surface
o Contour plots
o Shade plots (with either solid or pattern fill of the shaded regions using
  either color map0 (discrete colours) or colour map1 (continuous colours).
o Grid lines
o Lots of symbols and stroked fonts to choose from, all scalable
o Full control over boxes drawn, captions, fonts and placement of labels
o Speed: A yPlot plot finishes in about 3 times that of the corresponding
  compiled C version. Huh? Doesn't sound very fast, until you factor in the
  compiling time and development time (which can be VERY long if your C is
  not quite up to scratch. Like ours :-)
o Fast development due to the the interpreted nature of yPlot
o Lots of output devices, including X11, Postscript, Laserjet printers, PNG,
  JPEG and PLPlot metafiles for later rendering.
o PLUS: a tutorial and reference manual that demonstrates most of yPlot's
  capabilities with explanations every step of the way!
