An X-Ypiot
chart,
sometimes
called a scauerp/ot,
looks similar to a line
chart, but there is a significant difference between the two. Une charts plot a
value against a label (see the line chart on page 104), whereas X-Y plot charts
plot one value against another. X-Y plot charts are unique in that they take
categories two rows at a time and plot them against each othec
Another difference
between
Xoy plot charts
and line charts
is that on an X-Y
plot chart,
the rick marks
along
each axis (X is the horizontal
axis, Y the
vertical)
are spaced
according
to their value,
which
may not always
be at
regular intervals
because
of the potentially
random
nature
of the data.
On a
line chart,
one axis always
contains
text labels
which
are usually
evenly
spaced
for visual
clarity.
Variations
on the standard
K-Y plot chart
include
the following:
Lines
Only.
Draws
only the lines connecting
the points
in each
series;
does not draw
the markers
for each point.
Markers
Only.
Draws
only the markers
for each point;
does not
connect
the markers
with lines. This choice
makes an X-Y plot that
looks
like a traditional
scatter
plot. Scatter
plots
are primarily
used
to
see how different
data is grouped.
Pie chart
_ A pi_
chart
is a round_charx
in which
the size of each slice is proportional
to
the whole.
Pie charts
are unique
in that they only draw
one category
of data.
The
illustration
on the left shows
a typical pie chart.
Variations
on the standard
pie chart are:
•
Category
Titles.
Inserts
the category
rifles into the chart.
•
One
Tone
with
Category
Titles.
Shows
all the wedges
of the pie in
one
tone, with category
rides.
•
Ftrst
Wedge

that starts
near the
12-o'clock
position
out slighdy
from the rest of the pie.
•
All Exploded.
Pulis all the wedges
apart slighdy.
•
With
Percentages.

the percentage
of the whole
pie that each
