   | Yorick Language ReferenceMaking Plotsplg, y, x               plot graph of 1-D y vs. x
plm, mesh_args          plot quadrilateral mesh
 plc, z, mesh_args       plot contours of z
 plf, z, mesh_args       plot filled mesh, filling with z
 plv, v, u, mesh_args    plot vector field (u,v))
 pli, z, x0, y0, x1, y1  plot image
z
 pldj, x0, y0, x1, y1    plot disjoint lines
 plt, text, x, y         plot text at (x,y )
 The mesh_args may be zero, two, or three arguments as follows:
 
 omitted to use the current default mesh set by:
plmesh, mesh_args  set default quadrilateral mesh
 plmesh             delete current default quadrilateral mesh
 y, x
To set mesh points to (x, y ), which must be 2-D arrays of the
same shape, with at least two elements in each dimension.
 y, x, ireg
To set mesh points to (x, y ), as above, with a region number
array ireg. The ireg should be an integer array of the same
shape as y and x, which has a non-zero ``region number''
for every meaningful zone in the problem. The first row and column of
ireg do
not correspond to any zone, since there are one fewer zones along each
dimension than points in y and x.
 The plc command accepts the levs keyword to specify
the list of z values to be contoured; by default, eight linearly
spaced levels are generated.
 The plc and plmesh commands accept the triangle
keyword to specify a detailed triangulation map for the contouring algorithm.
Use the help, triangle for details.
 The plv command accepts the scale keyword to specify
the scaling factor to be applied to (u, v) before rendering the
vectors in (x, y) space; by default, the vector lengths are chosen
to be comparable to typical zone dimensions.
 The plm command accepts the boundary keyword, which
should be set to 1 if only the mesh boundary, rather than the mesh interior,
is to be plotted.
 The plm, plc, plf, and plv commands
accept the
region keyword to restrict the plot to only one region
of the mesh, as numbered by the ireg argument. The default region
is 0, which is interpreted to mean the every non-0 region of the mesh.
 The pli command produces a cell array; the x0, y0, x1, y1,
which are optional, specify the coordinates of the opposite corners of
the cell array.
 Numerous other keywords adjust the style of lines, text, etc.
