- function plot (...)
-
- # usage: plot (x, y)
- # plot (x1, y1, x2, y2, ...)
- # plot (x, y, fmt)
- #
- # If the first argument is a vector and the second is a matrix, the
- # the vector is plotted versus the columns (or rows) of the matrix.
- # (using whichever combination matches, with columns tried first.)
- #
- # If the first argument is a matrix and the second is a vector, the
- # the columns (or rows) of the matrix are plotted versus the vector.
- # (using whichever combination matches, with columns tried first.)
- #
- # If both arguments are vectors, the elements of y are plotted versus
- # the elements of x.
- #
- # If both arguments are matrices, the columns of y are plotted versus
- # the columns of x. In this case, both matrices must have the same
- # number of rows and columns and no attempt is made to transpose the
- # arguments to make the number of rows match.
- #
- # If both arguments are scalars, a single point is plotted.
- #
- # If only one argument is given, it is taken as the set of y
- # coordinates and the x coordinates are taken to be the indices of the
- # elements, starting with 1.
- #
- # To see possible options for FMT please see plot_opt.
- #
- # Examples:
- #
- # plot (x, y, "@12", x, y2, x, y3, "4", x, y4, "+")
- #
- # y will be plotted with points of type 2 ("+") and color 1 (red).
- # y2 will be plotted with lines.
- # y3 will be plotted with lines of color 4.
- # y4 will be plotted with points which are "+"s.
- #
- # plot (b, "*")
- #
- # b will be plotted with points of type "*".
