Badly designed graphs. These graphs show the same data. In the
upper
version, poor

size are changed unnecessarily, and are inconsistent with the main text. In the
lower
version, the
vertical scaling and fonts have been partially corrected, but unnecessary ornamentation has been
introduced, and the fonts are still too small. The grid lines and heavy border now greatly outweigh
the data being presented
primarily a demonstration of the kinds of improvement that a careful researcher can
achieve. The underlying point is that care is needed. A graph can be the central
element of a write-up, the place where the results are demonstrated and the case
made for support of a hypothesis. Great care is needed to ensure that graphs are
effective at communicating results.
In these examples, the graphs are rectangular rather than square, with the legends
placed in spare space within the body of the graph. The legend needs to be placed
