Add an Intervals Column

You can generate an interval column based on a numeric column (database column or calculated column) or a database text column.

When you generate an interval column based on a numeric column (database column or calculated column) and a specified interval, the calculated new column is numeric type.
When you generate an interval column from a database text column and a specified classification, the calculated new column is text type.

Add an Intervals Column when a numeric column is selected

Follow the below steps to add an Intervals column to the entity.

From the Entities panel on the left, select an entity. In this example, we have selected the 'FactInternetSales' entity.
Click the More button and then select the Add Intervals Column option from the list under the Quickly Create category.

Add Intervals Column dialog box is displayed.
Enter the Name of the new intervals column.
Select the numeric column from the current table from the Field dropdown list.

The Group Type option is displayed as Custom by default, and five intervals are displayed by default according to the maximum and minimum values of the column in the database. The WAX expression is also autogenerated.

You can manually add or delete the intervals, edit the intervals range, and modify the interval's name. If there is no data in the database, it will display No data found in the Group panel, and users can still add groups manually. If there is only one row of data, only one category will be displayed by default.
Note: The start value of the first set of intervals and the end value of the last set of intervals can be left blank, but if a group has neither a start value nor an end value, the group is invalid and you need to delete the group to save it.
If you change the Group Type to Bins, the Interval text box is displayed, and the default value is the difference between the maximum and minimum values currently listed in the database divided by five. If the database has no data or only one piece of data, the default value of the interval is empty, and the user can manually modify the interval size.

The maximum range of a single interval should be less than 1000. Otherwise, an error message Interval count exceeds upper limit of 1000 is displayed.
Click the Add button. The added intervals column will be displayed under the chosen entity in the Entities panel along with its other attributes.

Note: You cannot edit the autogenerated WAX expression here, but you can copy it.
