NAME

       plmeridians - Plot latitude and longitude lines.

SYNOPSIS

       plmeridians(mapform, dlong, dlat, minlong, maxlong, minlat, maxlat)

DESCRIPTION

       Displays latitude and longitude on the current plot.  The lines are plotted in the current color and line style.

       Redacted form:  General: plmeridians(mapform, dlong, dlat, minlong, maxlong, minlat, maxlat) F95, Java, Perl/PDL, Python: Not implemented?

       This function is used in example 19.

ARGUMENTS

       mapform (void (*) (PLINT, PLFLT *, PLFLT *), input)
	      A  user  supplied function to transform the coordinate  longitudes and latitudes to a plot coordinate system.   By using this trans-
	      form, we can change from a longitude,  latitude coordinate to a polar stereographic project, for	example.   Initially,  x[0]..[n-1]
	      are  the longitudes and y[0]..y[n-1]  are the corresponding latitudes.  After the call to mapform(), x[]	and y[] should be replaced
	      by the corresponding plot coordinates.   If no transform is desired, mapform can be replaced by NULL.

       dlong (PLFLT, input)
	      The interval in degrees at which the longitude lines are to be plotted.

       dlat (PLFLT, input)
	      The interval in degrees at which the latitude lines are to be plotted.

       minlong (PLFLT, input)
	      The value of the longitude on the left side of the plot.	The value of minlong must be less than	the  value  of	maxlong,  and  the
	      quantity maxlong-minlong must be less than or equal to 360.

       maxlong (PLFLT, input)
	      The value of the longitude on the right side of the plot.

       minlat (PLFLT, input)
	      The  minimum  latitude  to be plotted on the background.	 One can always use -90.0 as the boundary outside the plot window  will be
	      automatically eliminated.  However, the program will be  faster if one can reduce the size of the background plotted.

       maxlat (PLFLT, input)
	      The maximum latitudes to be plotted on the background.   One can always use 90.0 as the boundary outside the plot  window   will	be
	      automatically eliminated.

NAME

       plptex3 - Write text inside the viewport of a 3D plot.

SYNOPSIS

       plptex3(x, y, z, dx, dy, dz, sx, sy, sz, just, text)

DESCRIPTION

       Writes text at a specified position and inclination and with a specified shear within the viewport.  Text is clipped at the viewport bound-
       aries.  The reference point of a string lies along a line passing through the string at half the height of a capital letter.  The  position
       of  the	reference point along this line is determined by just, and the reference point is placed at world coordinates (x, y, z) within the
       viewport. The inclination and shear of the string is specified in terms of differences of world coordinates making it easy  to  write  text
       parallel to a line in a graph.

       Redacted form: plptex3(x, y, z, dx, dy, dz, sx, sy, sz,	just, text)

       This function is used in example 28.

ARGUMENTS

       x (PLFLT, input)
	      x coordinate of reference point of string.

       y (PLFLT, input)
	      y coordinate of reference point of string.

       z (PLFLT, input)
	      z coordinate of reference point of string.

       dx (PLFLT, input)
	      Together	with  dy and dz, this specifies the inclination of  the string.  The baseline of the string is parallel to a line  joining
	      (x, y, z) to (x+dx, y+dy, z+dz).

       dy (PLFLT, input)
	      Together with dx and dz, this specifies the inclination of the string.

       dz (PLFLT, input)
	      Together with dx and dy, this specifies the inclination of the string.

       sx (PLFLT, input)
	      Together with sy and sz, this specifies the shear of  the string.  The string is sheared so that the characters are  vertically par-
	      allel to a line joining (x, y, z) to (x+sx, y+sy, z+sz). If sx = sy = sz = 0.) then the text is not sheared.

       sy (PLFLT, input)
	      Together with sx and sz, this specifies shear of the string.

       sz (PLFLT, input)
	      Together with sx and sy, this specifies shear of the string.

       just (PLFLT, input)
	      Specifies  the  position	of  the  string  relative  to  its reference point.  If just=0., the reference point is at the left and if
	      just=1., it is at the right of the string.  Other values of just give intermediate justifications.

       text (const char *, input)
	      The string to be written out.
