x (PLFLT_VECTOR(3plplot), input)
A vector containing the x coordinates at which the function is evaluated.
y (PLFLT_VECTOR(3plplot), input)
A vector containing the y coordinates at which the function is evaluated.
z (PLFLT_MATRIX(3plplot), input)
A matrix containing function values to plot. Should have dimensions of nx by ny.
nx (PLINT(3plplot), input)
Number of x values at which function is evaluated.
ny (PLINT(3plplot), input)
Number of y values at which function is evaluated.
opt (PLINT(3plplot), input)
Determines the way in which the surface is represented. To specify more than one option just add
the options, e.g. DRAW_LINEXY + MAG_COLOR opt=DRAW_LINEX : Lines are drawn showing z as a function
of x for each value of y[j] . opt=DRAW_LINEY : Lines are drawn showing z as a function of y for
each value of x[i] . opt=DRAW_LINEXY : Network of lines is drawn connecting points at which
function is defined. opt=MAG_COLOR : Each line in the mesh is colored according to the z value
being plotted. The color is used from the current cmap1. opt=BASE_CONT : A contour plot is drawn
at the base XY plane using parameters nlevel and clevel. opt=DRAW_SIDES : draws a curtain between
the base XY plane and the borders of the plotted function.
clevel (PLFLT_VECTOR(3plplot), input)
A vector containing the contour levels.
nlevel (PLINT(3plplot), input)
Number of elements in the clevel vector.
