Scale Decide on an appropriate scale for each axis.

The scale refers to the min and max numbers used on each axis. They may or may not begin at zero.

The min and max numbers used for the scale should be a little lower than the lowest value and a little higher than the highest value.

This allows you to have a smaller range which emphasizes the comparisons/trends in the data.
