Note The Custom option is used for classifications that do not follow a set
scheme or pattern and are customized by the user. If you change the
symbolization of a class in an existing classification, the Vary By option will
change to Custom automatically and any new classes that are added to the
classification will be assigned the default symbols for that layer's geometry
type (for example, green in color).

select a color scheme.

different legend classes.
• Sequential–Displays a color that progresses from low to high (or high

extremes at both ends of the data range.
Then, select a color pattern from the Pattern drop-down list.

the darkest color represent the lowest value and the lightest color represent
the highest value (or vice versa).
