2. What was happening during the
flat section of the graph?
Obviously not any school work!

3. There are lots of graphs on the Internet
about Sales and Market Share of Gaming
Computers, Consoles, and Software.
As shown in this
Horizontal Bar Chart,
the global game
market is worth
many billions of
dollars and growing
rapidly.

4. The following slides show several
different types of Column Graphs:
Grouped Columns
Stacked Columns
Side by Side Comparison Columns
These graphs have been used in the real
world for representing Sales and Market
Share amongst the rival manufacturers of
computer gaming equipment.

7. The Title and Labels on Graphs need to
be read very carefully.
Many graphs are for “Projected”,
“Estimated”, “Forecast”, “Predicted”,
“Extrapolated”, or “Expected” values.
They are not actual sales or situations
which have occurred in the real world, but
only things which might possibly happen,
(or may not even happen at all).

10. The Title on any graph always needs to be
read very carefully.
Many graphs are only for one particular
month of successful sales or performance.
They do not necessarily indicate longer
term reality.
The single month of great product
performance may in fact not be
sustainable.

14. Line Graphs are sometimes used for
plotting sales, but they do not seem to be
as popular as Column Graphs.
Sometimes line graphs are coloured in
underneath the lines. This gives the graph
stronger impact value, but it can also
make the graph difficult to read.
Pie Charts are not used very often, and
Stem and Leaf Plots are hardly used at all.

21. Perhaps the reason for the flat
section of no work being done
on the school project, was not
due to time spent distracted on
computer gaming after all.
