1. The diagrams should be simple.

2. Each diagram must be given a clear, concise and suitable title without damaging clarity.

3. A proper proportion between height and width must be maintained in order to avoid an unpleasant look.

4. Select a proper scale; it should be in even numbers or in multiples of five or ten.

e.g. 25,50, 75 or 10, 20, 30, 40, .... etc. But no fixed rule.

5. In order to clear certain points, always put footnotes.

6. An index, explaining different lines, shades and colors should be given.

7. Diagrams should be absolutely neat and clean.

•   "The important point that must be borne in mind at all times that the pictorial representation chosen for any situation must depict the true relationship and point out the proper conclusion. Above all the chart must be honest." .... C. W. LOWE.
