Produce a horizontal bar graph from two vectors of x-y data.
If only one argument is given, it is taken as a vector of y-values and the x coordinates are taken to be the indices of the elements.
The default width of 0.8 for the bars can be changed using w.
If y is a matrix, then each column of y is taken to be a separate bar graph plotted on the same graph. By default the columns are plotted side-by-side. This behavior can be changed by the style argument, which can take the values
"grouped"
(the default), or"stacked"
.The optional return value h provides a handle to the bar series object. See
bar
for a description of the use of the bar series.The optional input handle h allows an axis handle to be passed. Properties of the patch graphics object can be changed using prop, val pairs.
