plm: Plot a Mesh

Calling Sequence

...

plm([y,x][,ireg][,<keylist>])

Description

Plot a mesh of y versus x. y and x must be 2D arrays with equal dimensions. If present, ireg must be a 2D region number array for the mesh, with the same dimensions as x and y. The values of ireg should be positive region numbers, and zero for zones which do not exist. The first row and column of ireg never correspond to any zone, and should always be zero. The default ireg is 1 everywhere else.

The y, x, and ireg arguments may all be omitted to default to the mesh set by the most recent plmesh call.

Keyword Arguments

The following keyword argument(s) apply only to this function.

boundary = 0/ 1

If present, the boundary keyword determines whether the entire mesh is to be plotted (boundary= 0, the default), or just the boundary of the selected region (boundary= 1).

inhibit = 0/ 1/ 2/ 3

If present, the inhibit keyword causes the (x(, j), y(, j)) lines to not be plotted (inhibit= 1), the (x(i,), y(i,)) lines to not be plotted (inhibit= 2), or both sets of lines not to be plotted (inhibit= 3). By default (inhibit= 0), mesh lines in both logical directions are plotted.

The following additional keyword arguments can be specified with this function:

legend, hide, type, width, color, region

See ``Plot Function Keywords'' on page  for detailed descriptions of these keywords.

Example

The mesh set by the plmesh function call in the preceding example may be plotted simply by calling plm with no arguments:

plm ()
