                            L_XYGRAPH()


Syntax:       L_XYGRAPH(<expN1>,<expN2>,<expN3>,<expN4>,
              <expN5>,<expN6>,<expN7>,<array1>,<array2>,
              <expN8>,<expN9>...[<array_n>,<array_n+1>,
              <expN8+n>,<expN9+n>])

Purpose:      To draw an xy graph on the screen using the
              specified data.

Arguments:    <expN1> is the x coordinate of the upper
              left corner of the graph.

              <expN2> is the y coordinate of the upper
              left corner of the graph.

              <expN3> is the x coordinate of the lower
              right corner of the graph.

              <expN4> is the y coordinate of the lower
              right corner of the graph.

              <expN5> is the color code for the color of
              the axes.

              <expN6> is the maximum value represented by
              the horizontal axis.

              <expN7> is the maximum value represented by
              the vertical axis.

              <array1> is the data to be plotted as the
              horizontal coordinates of the first set of
              points

              <array2> is the data to be plotted as the
              vertical coordinates of the first set of
              points

              <expN8> is the color code for the first set
              of points and the line joining them.

              <expN9> is the style in which the first set
              of points are to be plotted.

              <array_n> is the data to be plotted as the
              horizontal coordinates of the final set of
              points.

              <array_n+1> is the data to be plotted as the
              vertical coordinates of the final set of
              points.

              <expN8+n> is the color code for the final
              set of points.

              <expN9+n> is the style in which the final
              set of points are to be plotted.


Returns:      Nothing.


Usage:        They styles available for plotting points
              are as follows:

              Style 1 : A simple point.
              Style 2 : '+'.
              Style 3 : 'x'.
              Style 4 : A point in a box.
              Style 5 ; '*'.
