SYNOPSIS
SUBROUTINE PLOT9(Y,X,Char,N,Ymin,Ymax,Xmin,Xmax,Yaxid,Xaxid,Plchid)

DESCRIPTION
PLOT9(3f) yields a one-page printer plot of y(i) versus x(i):
1. With special plot characters;
2. With the vertical (y) axis min and max and the horizontal (x) axis min and max values specified by the data analyst; and
3. With hollerith labels (at most 6 characters) for the vertical axis variable, the horizontal axis variable, and the plotting character variable also being provided by the data analyst.

The ’special plotting character’ capability allows the data analyst to incorporate information from a third variable (aside from Y and X) into the plot.

The plot character used at the i-th plotting position (that is, at the coordinate (X(i),Y(i))) will be

1 if char(i) is between
  0.5 and 1.5
2 if char(i) is between
  1.5 and 2.5 [char46] [char46] [char46]
9 if char(i) is between
  8.5 and 9.5
0 if char(i) is between
  9.5 and 10.5 a if char(i) is between 10.5 and 11.5 b if char(i) is between 11.5 and 12.5 c if char(i) is between 12.5 and 13.5 [char46] [char46] [char46] w if char(i) is between 32.5 and 33.5 x if char(i) is between 33.5 and 34.5 y if char(i) is between 34.5 and 35.5 z if char(i) is between 35.5 and 36.5 x if char(i) is any value outside the range
0.5 to 36.5.

The use of the YMIN, YMAX, XMIN, and XMAX specifications allows the data analyst to control fully the plot axis limits, so as, for example, to zero-in on an interesting sub-region of a previous plot.

The use of hollerith identifying labels allows the data analyst to automatically have the plots labeled. This is particularly useful in a large analysis when many plots are being generated.
