In-Depth Information
In the preceding example, the total flights in
Group A
(represented by the blue bars)
correspond to those coming from outside the US, arriving at Chicago, and performed
by US carriers, as depicted in the corresponding current selections box on the left.
Group B
(represented by the brown bars) covers flights departing from Chicago,
bound to California, and performed by US carriers as well, as depicted in the current
selections box on the right.
We can easily see how the amount of flights performed by
Group A
is greater to that
of
Group B
during the first five months of 2011, it is almost equal during June and
July, and it is lower during the rest of the year.
