Figures A graph should help to better understand the textual description of the data. An example of a poor graph is shown below. As you can see from the example, this was clearly too much. Axes should be clearly labelled and legible. Enclosing the units in parentheses is an excellent way to denote them.
Proper scales are extremely important.
Improper scaling may easily distort the proportions in a graphical illustration of the data. Do not use too many graduations along the axes. Too many grid lines are con fusing rather than aiding. As a guideline for reproducing original records, choose a scaling with graduations approximately the same as those of the recording instrument used. If the origin does not appear on the graph, break the major axes to indicate this fact.
