Graphing
techniques: the good, the bad and the ugly...
If your problem
solution includes a graph, e.g. voltage vs. time, don't forget the following
essential characteristics of a good graph:
|
- The graph must
have a title - usually a simple title is best.
|
|
- Both x and y axes
must be properly labeled with labels and units (e.g. time (s), voltage
(V)
|
|
- Make sure the axes
are scaled appropriately, with convenient major and minor tickmarks
|
|
- If there is more
than one plot on a single graph, make sure both curves are clearly labeled
|
|
- If the graph is
computer generated, don't let the computer graphing format violate the
above rules. If necessary, hand annotate the graph to make sure it follows
the rules.

Here's an example of a good graph:
Here's a poor graph - what's missing?
