doubts about the clarity of the title, you should use a longer title
instead of running the risk of having a title that confuses the reader
or a title the reader will not understand.
The title should encompass the subject of the chart, the coverage the
data provides, and the time period. Look at the following title of a
chart and apply all the necessary elements of a title.
MAJOR AIRCRAFT ACCIDENTS
BY PHASE OF FLIGHT
U.S. ARMY AVIATION COMMAND
FORT RUCKER, AL
This title shows all the necessary elements: (1) subject of the chart
major aircraft accidents, (2) crossreference by phase of flight, (3)
the coverage U.S. Army Aviation Command, Fort Rucker, AL, and (4) time
period FY 86.
You should not break a title in phrases that do not make any sense or
are not complete thoughts. Each line of a title should represent a
complete thought. If each line of a title is not a complete thought,
the title often confuses the reader. Consider using the following as
the title for a chart:
ACCIDENTS BY PHASE
Now compare this title with the title in the preceding paragraph. Each
line of the proposed title (above) does not provide a complete thought
and often confuses the reader. The other title gives a complete thought
in each line and helps the reader understand what data the chart
contains. The proposed title is an example of how a title improperly
phrased can confuse the reader.
This lesson continues its discussion of selection, planning and
design, and construction of charts as they apply to the
different types of charts as it presents them.
d. Drawing Tools for Charts. When preparing a chart, you use many
basic drawing tools, such as a T square, scale ruler, triangles, etc.
You use the basic drawing equipment and materials in the production of
charts to present data (figure 18). Before beginning any project, you
must ensure that your tools are clean so they will not leave smudges and
ruin the project.
