Refresh the preview when a change occurs | Updates the data view on the Query Preview tab when a change occurs. This option is selected by default. |
Maximum number of rows for previews | Limits the number of rows that appear on the Query Preview tab. The default number is 5000. |
Keep queries compatible with JMP 12 by default | Maintains query compatibility with JMP 12. When you open a query that is marked JMP 12 compatible in JMP 13 or later, features that create compatibility problems are hidden regardless of how the preference is set. |

The minimum value is -1 (no limit). The maximum value is 1 billion. By default, if the categorical column has more than 1 million rows, JMP does not automatically retrieve the unique category levels. |

Default filter type for categorical columns | Specifies a List Box as the default filter type for categorical columns. |
Fallback filter type for categorical columns | Specifies a Contains filter as the default filter type for categorical columns when the number of rows cannot be determined or the query is canceled. |
