22 ## Given two vectors of x-y data, @code{bar} produce a bar graph. |
|
3426
|
23 ## |
|
2311
|
24 ## If only one argument is given, it is taken as a vector of y-values |
|
|
25 ## and the x coordinates are taken to be the indices of the elements. |
|
3426
|
26 ## |
|
6540
|
27 ## If @var{y} is a matrix, then each column of @var{y} is taken to be a |
|
|
28 ## separate bar graph plotted on the same graph. By default the columns |
|
|
29 ## are plotted side-by-side. This behavior can be changed by the @var{style} |
|
|
30 ## argument, which can take the values 'group' (the default), or 'stack'. |
|
|
31 ## |
|

|
32 ## If two output arguments are specified, the data are generated but |
|
|
33 ## not plotted. For example, |
|

|
34 ## |
|

|
35 ## @example |
|
|
36 ## bar (x, y); |
