What are the nine great features of a great graph

Graphs are done on graph paper or on a computer.
2. Good scaling:
a. Your scale should be easy to interpret.
i. One square or tic mark could represent 1, 2, 5, 10, …
ii. A graph unit represents a unit of 1, 10, 20, 100, 0.1.
iii. The scale should NOT change along an axis.
iv. You can, however, use two different vertical (y) axes, with different
scales for each one.
v. Your data should NOT be clumped in one region of your graph; you
should scale your graph so that your data is distributed across each
axis.
vi. Leave room on your paper for axis labels, numbers, graph title, etc.
3. If you are making your graph on graph paper, use a ruler or straight edge to draw
your lines.
4. The dependent variable is usually plotted on the y-axis and the independent
variable is usually plotted on the x-axis.
5. Put "tick" marks on the axes and corresponding numbers next to the tick marks.
6. Label what the axes represent by including the measurement and its units.
Examples: Time (minutes), Distance (mm), etc.
7. Your graph should have a descriptive title. The reader should know what the
graph is about by reading the title.
Note: Just repeating the axis labels (ex: Distance vs. Time), does not make a
good title. The title has to describe how you conducted your experiment or what
the experiment was about.
8. Data points should be represented clearly, with easy to distinguish symbols.
9. If you are plotting more than one set of data on the same graph, include a key or
legend. Use can use different colors, symbols or types of lines (solid, dashed) to
identify different conditions or subjects.
