Construction of Various Types of Charts.
a. Bar Charts. Generally, charts show the relationship between
several items. There are two types of bar charts. A vertical bar or
column chart uses vertical bars or columns to represent the data on the
chart, and a horizontal bar chart uses horizontal bars or columns to
represent the data on the chart.
(1) Vertical bar or column chart. Generally, you use vertical bar
or column charts to compare data for a given item at the same or
different times. For example, it could compare the procurements for the
month of January or an inventory for 30 June.
A simple column chart has vertical bars extending from the base or zero
line to a plotted point. The appearance of the chart is important
because a welldesigned and constructed chart attracts and holds the
reader's attention.
