BAR(Y) draws a bar graph of the elements of vector Y.
BAR(X,Y) draws a bar graph of the elements of vector Y at
the locations specified in vector X. The X-values must
be in ascending order. If the X-values are not evenly spaced, the
interval chosen is not symmetric about each data point. Instead,
the bars are drawn midway between adjacent X-values. The endpoints
simply adopt the internal intervals for the external ones needed.
If X and Y are matrices the same size, one bar graph per column
[XX,YY] = BAR(X,Y) does not draw a graph, but returns vectors
X and Y such that PLOT (XX,YY) is the bar chart.

BAR(X,'linetype') or BAR(X,Y,'linetype') uses the plot linetype
specified. See PLOT for details.
