20 ## usage: plot (x, y) |
|
|
21 ## plot (x1, y1, x2, y2, ...) |
|
|
22 ## plot (x, y, fmt) |
|
|
23 ## |
|
|
24 ## If the first argument is a vector and the second is a matrix, the |
|
|
25 ## the vector is plotted versus the columns (or rows) of the matrix. |
|
|
26 ## (using whichever combination matches, with columns tried first.) |
|
|
27 ## |
|
|
28 ## If the first argument is a matrix and the second is a vector, the |
|
|
29 ## the columns (or rows) of the matrix are plotted versus the vector. |
|
|
30 ## (using whichever combination matches, with columns tried first.) |
|
|
31 ## |
|
|
32 ## If both arguments are vectors, the elements of y are plotted versus |
|
|
33 ## the elements of x. |
|
|
34 ## |
|
|
35 ## If both arguments are matrices, the columns of y are plotted versus |
|
|
36 ## the columns of x. In this case, both matrices must have the same |
|
|
37 ## number of rows and columns and no attempt is made to transpose the |
|
|
38 ## arguments to make the number of rows match. |
|
|
39 ## |
|
|
40 ## If both arguments are scalars, a single point is plotted. |
|
|
41 ## |
|
|
42 ## If only one argument is given, it is taken as the set of y |
|
|
43 ## coordinates and the x coordinates are taken to be the indices of the |
|
|
44 ## elements, starting with 1. |

|
|
50 ## plot (x, y, "@12", x, y2, x, y3, "4", x, y4, "+") |
|
|
51 ## |
|
|
52 ## y will be plotted with points of type 2 ("+") and color 1 (red). |
|
|
53 ## y2 will be plotted with lines. |
|
|
54 ## y3 will be plotted with lines of color 4. |
|
|
55 ## y4 will be plotted with points which are "+"s. |
|
|
56 ## |
|
|
57 ## plot (b, "*") |
|
|
58 ## |
|
|
59 ## b will be plotted with points of type "*". |
