draw package: latest report



Hello,

For those who might be interested, this is a list of new drawing 
features in Maxima 5.14:

* More options for contour plots.
* 3d objects in spherical and cylindrical coordinates.
* Option unit_vectors for plotting 2d and 3d vector fields.
* New options for axis tics, colors, types and widths.
* Explicit filled functions enhanced.
* Implicit surfaces.
* 3d cartography.
* New terminals animated_gif and wxt (not sure if they work on
  windows systems, since wgnuplot is not compiled for all terminals)
* Now graphics object 'points accepts one-column, two-column,
  one-row and two-row matrices in 2d, and three-column and
  three-row matrices in 3d.
* I have rewritten the statistical graphics functions of package 
descriptive.
  They now depend on package draw and can use all the options defined
  in this package. These are the current statistical graphics functions:
   - scatterplot (new)
   - histogram (rewritten)
   - barsplot (rewritten)
   - piechart (new)
   - boxplot (rewritten)


For help:
