Equal Count: Divides a set of attribute values so that each has an equal proportion in the data distribution. - Click on the Classes drop down to choose the number of classes represented.

possible for a given page size. To set a scale other than the default, choose the desired scale from the drop-down menu.
When a new scale is selected, the orange bounding rectangle and the map extents will change to reflect the new printable area.
Example

Data Table:
If a feature is selected, an option to include the data table will be available. This option is not available when creating a .pdf or .jpg.
If the Data Table checkbox is checked, the feature information (attributes) will be included in the printable map. However, it is recommended to leave this option unchecked, as it reduces the printable map size dramatically. If descriptive (attribute) information is required, export to a comma separated values (.csv) file for Excel or create a Property Report for a Tax Parcel.
Optionally, create a .pdf or .jpeg image of the map.
