PLPTEX3(3plplot)						    PLplot API							  PLPTEX3(3plplot)

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.

NAME

       plgradient - Draw linear gradient inside polygon

SYNOPSIS

       plgradient(n, x, y, angle)

DESCRIPTION

       Draw  a	linear	gradient using colour map 1 inside the polygon defined by the n points (x[i], y[i]).  Interpretation of the polygon is the
       same as for plfill(3plplot).  The polygon coordinates and the gradient angle are all expressed in world coordinates.  The angle from the  x
       axis  for  both	the  rotated coordinate system and the gradient vector is specified by angle.  The magnitude of the gradient vector is the
       difference between the maximum and minimum values of x for the vertices in the rotated coordinate system.  The origin of the gradient  vec-
       tor  can  be interpreted as being anywhere on the line corresponding to the minimum x value for the vertices in the rotated coordinate sys-
       tem.  The distance along the gradient vector is linearly transformed to the independent variable of colour map 1 which ranges  from  0.	at
       the  tail  of the gradient vector to 1. at the head of the gradient vector.  What is drawn is the RGBA colour corresponding to the indepen-
       dent variable of colour map 1.  For more information about colour map 1 (see the PLplot documentation).

       Redacted form: plgradient(x,y,angle)

       This function is used in examples 25,30.

ARGUMENTS

       n (PLINT, input)
	      Number of vertices in polygon.

       x (PLFLT *, input)
	      Pointer to array with x coordinates of vertices.

       y (PLFLT *, input)
	      Pointer to array with y coordinates of vertices.

       angle (PLFLT, input)
	      Angle (degrees) of gradient vector from x axis.
