Axes
tab, mark the
Show Grid

a visible grid to the chart as well as place the labels alongside the axes, which
takes less space. Click on

The resulting chart is shown in the following screenshot. The Y-axis shows the
number of transported passengers while the X-axis shows the amount of transported
mail. The bubble size indicates how many flights (departures) have been performed
by each carrier.
We can immediately see there are carriers that only transport mail, such as
United
Parcel Service
, and those that only carry passengers, such as
Southwest Airlines Co
.
In fact, most carriers seem to either do one or the other, not both.
Make a few selections on the
Carrier's Operating Region
listbox and you might
gain some interesting insights. Also notice how the unit of the chart's scale
changes between selections because we set the
Thousand
,
Million
, and
Billion Symbol
fields.
