Tip: Be careful NOT to use a line graph when the X-axis is a categorical (also called nominal or qualitative) variable. If the X-axis variable represents distinct groups (e.g., different schools) use a bar graph instead.
Include an example that shows how limiting the scale can lead to distorted interpretations.
