Graphs

A good graph should have

• a title,
• labels and units on both the x and the y axes,
• The scales of each axis should allow the data to fit nicely into the graph.
• The data points should show uncertainty bars, if appropriate.
• If there is a clear trend in the data, you may include a “best-fit line”, a straight line, or a curved line to best fit the data.

Here is an example of a good graph with the important aspects pointed out.
