Create a Plot3D


This function creates a new Plot3D and optionally initialises its attributes.

A Plot3D is a specialised form of Plot that provides facilities for producing 3D graphical output.


AstPlot3D astPlot3D( AstFrame frame, const float graphbox[ 6 ], const double basebox[ 6 ], const char options, ... )


Pointer to a Frame describing the physical coordinate system in which to plot. A pointer to a FrameSet may also be given, in which case its current Frame will be used to define the physical coordinate system and its base Frame will be mapped on to graphical coordinates (see below).

If a null Object pointer (AST__NULL) is given, a default 3-dimensional Frame will be used to describe the physical coordinate system. Labels, etc. may then be attached to this by setting the appropriate Frame attributes (e.g. Label(axis)) for the Plot.

An array giving the position and extent of the plotting volume (within the plotting space of the underlying graphics system) in which graphical output is to appear. This must be specified using graphical coordinates appropriate to the underlying graphics system.

The first triple of values should give the coordinates of the bottom left corner of the plotting volume and the second triple should give the coordinates of the top right corner. The coordinate on the horizontal axis should be given first in each pair. Note that the order in which these points are given is important because it defines up, down, left and right for subsequent graphical operations.

An array giving the coordinates of two points in the supplied Frame (or in the base Frame if a FrameSet was supplied) which correspond to the bottom left and top right corners of the plotting volume, as specified above. This range of coordinates will be mapped linearly on to the plotting area. The coordinates should be given in the same order as above.
Pointer to a null-terminated string containing an optional comma-separated list of attribute assignments to be used for initialising the new Plot3D. The syntax used is identical to that for the astSet function and may include " printf" format specifiers identified by " %" symbols in the normal way. If no initialisation is required, a zero-length string may be supplied.
If the " options" string contains " %" format specifiers, then an optional list of additional arguments may follow it in order to supply values to be substituted for these specifiers. The rules for supplying these are identical to those for the astSet function (and for the C " printf" function).

Returned Value

A pointer to the new Plot3D.
