plcont
PLCONT(3plplot) PLplot API PLCONT(3plplot)
NAME
plcont - Contour plot
SYNOPSIS
plcont(z, nx, ny, kx, lx, ky, ly, clevel, nlevel, pltr, pltr_data)
DESCRIPTION
Draws a contour plot of the data in z[nx][ny], using the nlevel contour levels specified by clevel. Only the region of the array from kx to
lx and from ky to ly is plotted out. A transformation routine pointed to by pltr with a pointer pltr_data for additional data required by
the transformation routine is used to map indices within the array to the world coordinates. See the following discussion of the arguments
and the PLplot documentation for more information.
Redacted form: [PLEASE UPDATE! ONLY PERL INFO IS LIKELY CORRECT!] F95: plcont(z, kx, lx, ky, ly, clevel, tr?) or plcont(z, kx, lx, ky, ly,
clevel, xgrid, ygrid) Java: pls.cont(z, kx, lx, ky, ly, clevel, xgrid, ygrid) Perl/PDL: plcont(z, kx, lx, ky, ly, clevel, pltr, pltr_data)
Python: plcont2(z, kx, lx, ky, ly, clevel)
This function is used in examples 9,14,16,22.
ARGUMENTS
z (PLFLT **, input)
Pointer to a vectored two-dimensional array containing data to be contoured.
nx, ny (PLINT, input)
Physical dimensions of array z.
kx, lx (PLINT, input)
Range of x indices to consider.
ky, ly (PLINT, input)
Range of y indices to consider.
clevel (PLFLT *, input)
Pointer to array specifying levels at which to draw contours.
nlevel (PLINT, input)
Number of contour levels to draw.
pltr (void (*) (PLFLT, PLFLT, PLFLT *, PLFLT *, PLPointer) , input)
Pointer to function that defines transformation between indices in array z and the world coordinates (C only). Transformation func-
tions are provided in the PLplot library: pltr0(3plplot) for identity mapping, and pltr1(3plplot) and pltr2(3plplot) for arbitrary
mappings respectively defined by one- and two-dimensional arrays. In addition, user-supplied routines for the transformation can be
used as well. Examples of all of these approaches are given in the PLplot documentation. The transformation function should have
the form given by any of pltr0(3plplot), pltr1(3plplot), or pltr2(3plplot). Note that unlike plshades(3plplot) and similar PLplot
functions which have a pltr argument, plcont requires that a transformation function be provided in the C interface. Leaving pltr
NULL will result in an error.
pltr_data (PLPointer, input)
Extra parameter to help pass information to pltr0(3plplot), pltr1(3plplot), pltr2(3plplot), or whatever routine that is externally
supplied.
