xtitle is the title for the x axis.
ytitle is the title for the y axis.
ztitle is the title for the z axis.
title is the main title, displayed above the plot.
rotx is the rotation angle (in degrees) around the x
rotz is the rotation angle (in degrees) around the z axis
(after applying the rotation around the x axis, if any).
contours specifies contour levels. If
contours is a scalar equal to integer 1 (e.g.,
/contours), then it says to show automatically selected
contours. Otherwise, if
contours is a real scalar, then
it specifies the desired number of contours to display, but the levels
are selected automatically. Otherwise, if
contours is an
array, then it specifies the contour levels to use.
/flat requests an orthographic view from above; i.e., a flat
The options beginning with
/l are followed by two or three
letters that say whether the x, y, and z axes should be linear
i) or logarithmic (
o). For example,
/lioi select linear x and z axes and logarithmic y axis, and
/looo selects logarithmic x, y, and z axes.
