The 3d examples are really good!
It seems not all of the mentioned examples run equally well on maxima-gcl.
Maxima-gcl complains about zero-divisor in examp. 3,4
I was not able to produce the last picture. The gnuplot version is 3.8k1-1
I got only the empty box.
best rgds,

| 1) Goal: the idea is not to create the ultimate plotting tool for
| Maxima. Rather, I have tried to make the maximum functionality available
| with the currently available tool (Gnuplot) and minimal effort. Simple
| operations should be easy and complex operations should be possible.
|
| 2) (New) "gnuplot" is now the default plotting format. The old gnuplot
| interface that utilizes the mgnuplot tcl-tk script is available as
| "mgnuplot". The old default maxima plotting package is still available
| as "openmath".
|
| 3) Three gnuplot terminals are available: default, ps and dumb. Each can
| either be displayed to the screen or saved to a file.
|
| 4) Several new plot_options are available:
| a) gnuplot_term = default, ps or dumb. default is default.
| b) gnuplot_out_file = false or filename. false is default. Output
| files are gnuplot format to be loaded in the gnuplot application for the
| default term, encapsulated postscript for the ps term and text for the
| dumb term.
| c) gnuplot_pm3d = true or false. false is default. Turns on the pm3d
| option available in newer versions of Gnuplot.
| d) gnuplot_preamble = string. "" is default. The preamble can contain
| an arbitrary string of Gnuplot commands. Multiple commands should be
| separated with semi-colons.
| e) gnuplot_curve_titles = list of (strings or default). [default] is
| default. The list of curve titles will be applied to the list of
| curves. If there are more curves than titles in the list, the list will
| wrap around. The special value default give the curves titles based on
| the 1d representation of the function name.
| f) gnuplot_curve_styles = list of strings. The styles wrap around in a
| manner similar to the titles. The strings themselves should be gnuplot
| commands appropriate for
| plot "file" with title "title <style>
| For details type "help plot" in gnuplot.
| g) gnuplot_default_term_command = string. Default is "". The gnuplot
| command to set the default terminal.
| h) gnuplot_ps_term_command = string. Default is "set size 1.5, 1.5;set
| term postscript eps enhanced color solid 24". The gnuplot command to set
| the ps terminal.
| g) gnuplot_default_term_command = string. Default is "set term dumb 79
| 22". The gnuplot command to set the dumb terminal.
|
| 5) More testing needs to be done, particularly with xmaxima and windows.
|
| Feedback on this interface will be greatly appreciated. This is the last
| feature I plan to add before working on the 5.9.1 release.
