MPLOT - Fortran subroutine to plot one or more functions.

Usage:

DIMENSION X(150,N),Y(150,N),NPNTS(N)
CALL MPLOT0(IGRID, IWIDTH, JLNGTH, NSBVL, NSBHL)
CALL MPLOT1(N, X, Y, NPNTS, IOUT)

Where:

N: is the number of curves to be plotted. This can be anything from one to ten.
X: is an array containing N sets of points to be plotted along the abscissa.
Y: is an array containing points to be plotted along the ordinate.
NPTS: is a vector containing the number of points in each curve.
IGRID: indicates the type of background for the plot. IGRID=0 implies a blank background with plotted points. IGRID=1 indicates that the X and Y axes should be printed on the graph along with the plotted points. IGRID=2 implies that X and Y grid lines should be placed on the graph along with the plotted points.
IWIDTH: represents the width of the graph in characters. MPLOT plots ten characters per inch in width on the printer or cards.
JLNGTH: represents the length down the page in character lengths (e.g. one character length = 1/6 inch) of the graph.
NSBVL: specifies the distance between vertical grid lines.
NSBHL: specifies the distance between horizontal grid lines.
IOUT: indicates the output unit. IOUT=6 specifies the printer.

Description:

MPLOT0 and MPLOT1 are two subroutines which go together to plot one or more graphs on an output unit.

A call to MPLOT0 specifies the type of background for the graph. If a call to MPLOT0 is not made before a call to MPLOT1, a standard set of parameters will be assumed. These defaults give a graph area of ten inches with grid lines spaced one inch apart.
