Select a Table and a Field:
Table
Designate a source table whose points, or in the case of non-point objects, centroids will be interpolated. All active map layers, with the exception of selections are listed
Field
The drop-down list displays all the numeric fields in the table you chose from the Table list. Choose the field or expression you want to use.
Ignore Zeroes or Blanks
Disabled for Dot Density. Check this box to ignore zero values and blank values in the table. Because you are creating a thematic map based on one field in a table, any zero or blank values in that field will cause the whole record to be ignored.
