ncl_gca man page

GCA (Cell array) — draws a cell array starting with a  rectangle specified by two corner points; this initial  rectangle is subdivided into subrectangles by  specifying an arbitrary number of divisions in the X  and Y directions; each subrectangle (or cell) is  assigned a color and drawn with that color.

Synopsis

CALL GCA (XP1, YP1, XP2, YP2, NXCLR, NYCLR, IXCLR, IYCLR, NXDO, NYDO, CLRIA)

C-Binding Synopsis

#include <ncarg/gks.h>

void gcell_array(const Grect *rect, const Gpat_rep *colr_array);

Description

XP1

(Real, Input) - X world coordinate of point 1.

YP1

(Real, Input) - Y world coordinate of point 1.

XP2

(Real, Input) - X world coordinate of point 2.

YP2

(Real, Input) - Y world coordinate of point 2.

NXCLR

(Integer, Input) - X dimension of the color index array  CLRIA.

NYCLR

(Integer, Input) - Y dimension of the color index array  CLRIA.

IXCLR

(Integer, Input) - The index of the starting column in  index array CLRIA.

IYCLR

(Integer, Input) - The index of the starting row in  index array CLRIA.

NXDO

(Integer, Input) - Number of cell elements to draw in  the X dimension.

NYDO

(Integer, Input) - Number of cell elements to draw in the Y dimension.

CLRIA

(Integer array, Input) - An array of color indices  dimensioned NXCLR x NYCLR which is  used to determine the color of each  cell drawn.

Usage

Points 1 and 2 must be diagonally opposite corner  points of a rectangle to be divided into NXDO cells in  the X dimension and NYDO cells in the Y dimension.

Access

To use GKS routines, load the NCAR GKS-0A library  ncarg_gks.
