NAME

       plimagefr - Plot a 2D matrix using color map1

SYNOPSIS

       plimagefr(idata, nx, ny, xmin, xmax, ymin, ymax, zmin, zmax, valuemin, valuemax, pltr, pltr_data)

DESCRIPTION

       Plot a 2D matrix using color map1.

       Redacted form:  General: plimagefr(idata, xmin, xmax, ymin, ymax, zmin, zmax, valuemin, valuemax, pltr, pltr_data)

       This function is used in example 20.

ARGUMENTS

       idata (PLFLT**, input)
	      A 2D array of values (intensities) to plot.  Should have dimensions idata[nx][ny].

       nx, ny (PLINT, input)
	      Dimensions of idata

       xmin, xmax, ymin, ymax (PLFLT, input)
	      Stretch  image  data  to	these  Plot coordinates.  idata[0][0] corresponds to (xmin, ymin) and idata[nx - 1][ny - 1] corresponds to
	      (xmax, ymax).

       zmin, zmax (PLFLT, input)
	      Only data between zmin and zmax (inclusive) will be plotted.

       valuemin, valuemax (PLFLT, input)
	      The minimum and maximum data values to use for value to color mappings.  A datum equal to or less than valuemin will be plotted with
	      color  0.0,  while a datum equal to or greater than valuemax will be plotted with color 1.0.  Data between valuemin and valuemax map
	      linearly to colors between 0.0 and 1.0.

       pltr (void (*) (PLFLT, PLFLT, PLFLT *, PLFLT *, PLPointer) , input)
	      Pointer to function that defines a transformation between the data in the array idata and world coordinates.  An input coordinate of
	      (0,  0) corresponds to the "top-left" corner of idata while (nx, ny) corresponds to the "bottom-right" corner of idata.  Some trans-
	      formation functions 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 trans-
	      formation can be used as well.  Examples of all of these approaches are given in the PLplot documentation.  The transformation func-
	      tion should have the form given by any of pltr0(3plplot), pltr1(3plplot), or pltr2(3plplot).

       pltr_data (PLPointer, input)
	      Extra  parameter	to help pass information to pltr0(3plplot), pltr1(3plplot), pltr2(3plplot), or whatever routine is externally sup-
	      plied.

NAME

       plw3d - Set up window for 3-d plotting

SYNOPSIS

       plw3d(basex, basey, height, xmin, xmax, ymin, ymax, zmin, zmax, alt, az)

DESCRIPTION

       Sets  up a window for a three-dimensional surface plot within the currently defined two-dimensional window.  The enclosing box for the sur-
       face plot defined by xmin, xmax, ymin, ymax, zmin and zmax in user-coordinate space is mapped into a box of world coordinate size basex	by
       basey  by  height so that xmin maps to -basex/2, xmax maps to basex/2, ymin maps to -basey/2, ymax maps to basey/2, zmin maps to 0 and zmax
       maps to height.	The resulting world-coordinate box is then viewed by an observer at altitude alt and azimuth az.   This  routine  must	be
       called  before plbox3(3plplot) or plot3d(3plplot).  For a more complete description of three-dimensional plotting see the PLplot documenta-
       tion.

       Redacted form: plw3d(basex, basey, height, xmin, xmax, ymin, ymax, zmin, zmax, alt, az)

       This function is examples 8,11,18,21.

ARGUMENTS

       basex (PLFLT, input)
	      The x coordinate size of the world-coordinate box.

       basey (PLFLT, input)
	      The y coordinate size of the world-coordinate box.

       height (PLFLT, input)
	      The z coordinate size of the world-coordinate box.

       xmin (PLFLT, input)
	      The minimum user x coordinate value.

       xmax (PLFLT, input)
	      The maximum user x coordinate value.

       ymin (PLFLT, input)
	      The minimum user y coordinate value.

       ymax (PLFLT, input)
	      The maximum user y coordinate value.

       zmin (PLFLT, input)
	      The minimum user z coordinate value.

       zmax (PLFLT, input)
	      The maximum user z coordinate value.

       alt (PLFLT, input)
	      The viewing altitude in degrees above the XY plane.

       az (PLFLT, input)
	      The viewing azimuth in degrees.  When az=0, the observer is looking face onto the ZX plane, and as az  is  increased,  the  observer
	      moves clockwise around the box when viewed from above the XY plane.
