28 ## Set up a plot grid with @var{rows} by @var{cols} subwindows and set the
29 ## current axes for plotting (@code{gca}) to the location given by @var{index}.
30 ##
31 ## If only one numeric argument is supplied, then it must be a three digit
32 ## value specifying the number of rows in digit 1, the number of
33 ## columns in digit 2, and the plot index in digit 3.
34 ##
35 ## The plot index runs row-wise; First, all columns in a row are numbered
36 ## and then the next row is filled.
37 ##
38 ## For example, a plot with 2x3 grid will have plot indices running as follows:
39 ## @tex
40 ## \vskip 10pt
41 ## \hfil\vbox{\offinterlineskip\hrule
42 ## \halign{\vrule#&&\qquad\hfil#\hfil\qquad\vrule\cr
43 ## height13pt&1&2&3\cr height12pt&&&\cr\noalign{\hrule}
44 ## height13pt&4&5&6\cr height12pt&&&\cr\noalign{\hrule}}}
45 ## \hfil
46 ## \vskip 10pt
47 ## @end tex
48 ## @ifnottex
49 ##
50 ## @example
51 ## @group
52 ## +-----+-----+-----+
53 ## | 1 | 2 | 3 |
54 ## +-----+-----+-----+
55 ## | 4 | 5 | 6 |
56 ## +-----+-----+-----+
57 ## @end group
58 ## @end example
59 ##
60 ## @end ifnottex
61 ##
62 ## @var{index} may also be a vector. In this case, the new axis will enclose
63 ## the grid locations specified. The first demo illustrates this:
64 ##
65 ## @example
66 ## demo ("subplot", 1)
67 ## @end example
68 ##
69 ## The index of the subplot to make active may also be specified by its axes
70 ## handle, @var{hax}, returned from a previous @code{subplot} command.
71 ##
72 ## If the option @qcode{"align"} is given then the plot boxes of the subwindows
73 ## will align, but this may leave no room for axis tick marks or labels.
74 ##
75 ## If the option @qcode{"replace"} is given then the subplot axis will be
76 ## reset, rather than just switching the current axis for plotting to the
77 ## requested subplot.
78 ##
79 ## The @qcode{"position"} property can be used to exactly position the subplot
80 ## axes within the current figure. The option @var{pos} is a 4-element vector
81 ## [x, y, width, height] that determines the location and size of the axes.
82 ## The values in @var{pos} are normalized in the range [0,1].
83 ##
84 ## Any property/value pairs are passed directly to the underlying axes object.
85 ##
86 ## If the output @var{hax} is requested, subplot returns the axis handle for
87 ## the subplot. This is useful for modifying the properties of a subplot
88 ## using @code{set}.
