Horizontal
and vertical bar charts display the magnitude of data with bars, each
of which represents a category of data (midpoint). The length (or
height) of the bars represents the value of the chart statistic for
the corresponding midpoint. Both horizontal and vertical bar charts
can be either two-dimensional or three-dimensional shapes, depending
on which procedure you choose.
Horizontal Bar Chart (GCHBRSUM (a)) shows a simple
two-dimensional, horizontal bar chart of total sales for three manufacturing
sites. Each site is a midpoint and is displayed
as a bar. The name of the site (the midpoint value) is printed on
the midpoint axis beside the bar. Midpoint values are, by default,
arranged in ascending alphabetical or numeric order from top to bottom
of the chart and labeled with the name or label of the chart variable.
The chart statistics,
in this case total sales for each site, are represented by the length
of the bars. The response axis displays the scale of values for the
chart statistic. The table of statistics to the right of the bars
displays the statistic for each bar. Both a column in the table and
the response axis are labeled with the name of the summary variable
and the type of statistic.
Vertical (Three-Dimensional) Bar Chart (GCHBRSUM (b)) shows the same
data presented as a three-dimensional, vertical bar chart. The two types of bar charts have essentially the same
characteristics except for where they display statistical values.
Horizontal bar charts by default display a table of statistic values
to the right of the bars. You can specify that vertical bar charts
display the statistic value above or inside of each bar.
