Displays a 3D plot of 2D data set

via the gnuplot
program.
`z`

If

and `x`

are specified, then they provide
the x and y coordinates for the columns and rows of `y`

.
They must be 1D data sets, with `z`

having as many elements
as the first dimension of `x`

, and `z`

having as
many elements as the second dimension of `y`

.
`z`

is the title for the x axis.
`xtitle`

is the title for the y axis.
`ytitle`

is the title for the z axis.
`ztitle`

is the main title, displayed above the plot.
`title`

is the rotation angle (in degrees) around the x
axis.
`rotx`

is the rotation angle (in degrees) around the z axis
(after applying the rotation around the x axis, if any).
`rotz`

specifies contour levels. If
`contours`

is a scalar equal to integer 1 (e.g.,
`contours``/contours`

), then it says to show automatically selected
contours. Otherwise, if

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.
`contours`

`/flat`

requests an orthographic view from above; i.e., a flat
image.

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, `/lio`

and
`/lioi`

select linear x and z axes and logarithmic y axis, and
`/looo`

selects logarithmic x, y, and z axes.
