SYNOPSIS

3d

DESCRIPTION

The 3d command switches C-PLOT to 3D mode. In 3D mode, the axes are drawn and the data is plotted using a 3D-perspective box.

The commands vi, to set the view point of the 3D box, and bo, to set the relative lengths of the 3D box, are available in 3D mode. See the vi and bo help files for more information.

The absolute size of the 3D box is the largest that just fits in the 2D window set by the window command, wi, without distorting the aspect ratio of the box.

When position arguments are used with the annotation or key drawing commands pn, zn, pk and zk, three arguments are required. The units of the position arguments are either data units, as in 2D mode, or box units, as used with the bo command.

In 3D mode, the gd 9 command (digitize) and the gd 4 and gd 5 commands (break data) are not available. The other gd modes and the sa command work with three columns of data, plus optional error-bar and pen-control values. Note, however, that only z-error bars are available in 3D mode.

In 3D mode, the commands ra, ro, np, ty and tx take extra arguments and/or prompt for extra values associated with the z axis.

LIMITATIONS

In its current state, the 3D functionality has some limitations. For one, circle symbols are drawn as flat 2D circles in 3D mode. Also, axis numbering and annotation is in fixed planes and orientation.
