Plot 3-D bar graph

`bar3(Y)bar3(x,Y)bar3(...,width)bar3(...,'`

`bar3` draws a three-dimensional bar graph.

`bar3(Y)` draws a three-dimensional
bar chart, where each element in `Y` corresponds
to one bar. When `Y` is a vector, the *x*-axis
scale ranges from `1` to `length(Y)`.
When `Y` is a matrix, the *x*-axis
scale ranges from `1` to `size(Y,1)` and
the elements in each row are grouped together.

`bar3(x,Y)` draws a bar chart
of the elements in `Y` at the locations specified
in `x`, where `x` is a vector defining
the *y*-axis intervals for vertical bars. The *x*-values
can be nonmonotonic, but cannot contain duplicate values. If `Y` is
a matrix, `bar3` clusters elements from the same
row in `Y` at locations corresponding to an element
in `x`. Values of elements in each row are grouped
together.

`bar3(...,width)` sets the
width of the bars and controls the separation of bars within a group.
The default `width` is `0.8`, so
if you do not specify `x`, bars within a group have
a slight separation. If `width` is `1`,
the bars within a group touch one another.

`bar3(...,'style')` specifies
the style of the bars.

`'detached'`displays the elements of each row in`Y`as separate blocks behind one another in the*x*direction.`'grouped'`displays*n*groups of*m*vertical bars, where*n*is the number of rows and*m*is the number of columns in`Y`. The group contains one bar per column in`Y`.`'stacked'`displays one bar for each row in`Y`. The bar height is the sum of the elements in the row. Each bar is multicolored, with colors corresponding to distinct elements and showing the relative contribution each row element makes to the total sum.

`bar3(...,LineSpec)` displays
all bars using the color specified by `LineSpec`.

`bar3(axes_handle,...)` plots
into the axes with the handle `axes_handle` instead
of into the current axes (`gca`).

`h = bar3(...)` returns a
vector of handles to surface objects, one for each created. When `Y` is
a matrix, `bar3` creates one surface object per
column in `Y`.
