J Module 25 focuses on using visuals common in business documents, including
charts, graphs, and clip art.
Numerous software packages offer pre-made clip art so users don’t have
to be artists at all, and most word processing programs have tools to create
simple charts, tables, and graphs.
However, a general appreciation of good design is important, regardless
of artistic skill. And with so much
emphasis on visuals in communication today, many people expect sophistication
when using visuals.
Visuals are used in the rough draft to:
·
See that ideas
are presented completely.
·
Find
relationships.
And in the final draft to:
·
Make points
vivid.
·
Emphasize
material.
·
Present
material more compactly and with less repetition.
A story is something that is happening, according to the data.
To find stories, look for relationships and changes.
Ever visual should tell a story, that is,
show the reader that something is happening, according to the data. Stories are often expressed as the title of
the visual—Salaries Grew by 27 Percent from 1990 to 2000. Good stories use strong verbs to clearly
show action. Titles without verbs—Salaries
from 1990 to 2000—tell the reader little or nothing about what has
happened.
To find stories, writers should analyze their
data carefully. Specifically writers
should
1.
Focus on a
topic.
2. Simplify the data.
3. Look for relationships and changes.
Sometimes, a graphic alone does not tell the complete story. In such cases, writers can use paired graphs—side-by-side comparisons that together tell the complete story. Because data can tell more than one story, writers must choose carefully which story they wish to tell. Data alone will not tell a story, and left to interpretation, data can confuse and frustrate audiences.
Yes! The visual must match the kind of story.
Visuals are not interchangeable, even if some students use them
interchangeably!
·
Use tables when
the reader needs to be able to identify exact values.
·
Use a chart or
graph when you want the reader to focus on relationships.
·
Use a pie chart
to compare a part to the whole.
·
Use a bar chart
or line graph to compare one item to another item or items over time.
žWhat design conventions
should I follow?
Check your visuals against the lists that follow.
Every visual should contain the
following six components:
1. A title that tells the story that the visual shows.
2. A clear indication of what the data are.
3. Clearly labeled units.
4. Labels or legends for axes, colors, symbols, and so forth.
5. The source of the data.
6. The source of the visual, if it’s reproduced.
Tables are numbers or words arranged in rows and columns; figures are everything else.
For effective tables, writers should
·
Use tables only
when they want the audience to focus on specific numbers. Graphs convey less
specific information but are always more memorable.
·
Use common,
understandable units. Round off to simplify the data (e.g., 35% rather than 35.27%;
34,000 rather than 33,942).
·
Provide column
and row totals or averages when they're relevant.
·
Put the items
they want readers to compare in columns rather than in rows to facilitate
mental subtraction and division.
·
When they have
many rows, screen alternate entries or double space after every five entries to
help readers line up items accurately.
To use pie charts effectively, writers should
·
Start at 12
o'clock with the largest percentage or the percentage they want to focus on. Go
clockwise to each smaller percentage or to each percentage in some other
logical order.
·
Make the chart
a perfect circle. Perspective circles distort the data.
·
Limit the
number of segments to five or seven. If their data have more divisions, combine
the smallest or the least important into a single "miscellaneous" or
"other" category.
·
Label the
segments outside the circle. Internal labels are hard to read.
To use bar charts effectively, writers should
·
Order the bars
in a logical or chronological order.
·
Put the bars
close enough together to make comparison easy.
·
Label both
horizontal and vertical axes.
·
Put all labels
inside the bars or outside them. When some labels are inside and some are
outside, the labels carry the visual weight of longer bars, distorting the
data.
·
Make all the
bars the same width.
·
Use different
colors for different bars only when their meanings are different: estimates as
opposed to known numbers, negative as opposed to positive numbers.
·
Avoid using
perspective. Perspective makes the values harder to read and can make
comparison difficult.
To use line graphs effectively, writers
should
·
Label both
horizontal and vertical axes.
·
When time is a
variable, put it on the horizontal axis.
·
Avoid using
more than three different lines on one graph. Even three lines may be too many
if they cross each other.
·
Avoid using
perspective. Perspective makes the values harder to read and can make
comparison difficult.
As suggested here, writers should use the specific visual that best
expresses the data they have. They
should avoid mixing and matching types, instead using the particular visual
that fits their needs.
Use
color carefully.
Avoid
decorative clip art in memos and reports.
Help students to resist the temptation to use color entirely for
decorative purposes by reminding them of cultural interpretations of color. In fact, though computer programs offer
almost limitless palettes of colors, writers must carefully choose the colors
they use, as well as the number.
To use color effectively, writers should
·
Use no more
than five colors when colors have meanings.
·
Use glossy
paper to make colors more vivid.
·
Be aware that
colors on a computer screen always look brighter than colors on paper.
Likewise, writers must take care when selecting and using clip
art. Like color, clip art used for
decorative purposes only may hurt a document or presentation rather than help
it. For instance, clip art that is biased—that
shows only European-American males, for instance, to represent a company that
may be more than 50 percent female—can offend readers or viewers.
Clip art that is only decorative is called chartjunk. Writers should avoid using chartjunk in
business documents, as it can confuse or mislead readers trying to interpret
the data. Internal presentations that
are informal may use chartjunk; however, most business documents are
better without chartjunk.
Be
sure that the visual is accurate and ethical.
Students should
double check visuals for accuracy and make sure they’re ethical. Even simple bar and line graphs can be
misleading if part of the scale is missing, or truncated. Truncated graphs are most acceptable when
the audience knows the basic data set well.
Data can also be distorted when the context is omitted.
Writers can take
steps to make visuals more accurate:
·
Differentiate
between actual and estimated or projected values.
·
When you must
truncate a scale, do so clearly with a break in the bars of in the background.
·
Avoid
perspective and three-dimensional graphs.
·
Avoid combining
graphs with different scales.
·
Use images of
people carefully in histographs to avoid sexist, racist, or other exclusionary
visual statements.
Only
if the table or graph is simple.
Visuals in presentations should be simple. Remind students that they can use the visuals from the document
if they are simple. To simplify a
complex table, writers can cut out some of the information round off the data
even more, or present the material in a chart rather than a table.
