Field Filters

Introduction

Field Filter gets data from a model field available in a Dataset. The filter's data type will depend on the data type of the field itself.

Setting up a Field Filter

When selecting Field Type as Field, you will need to specify the path to the field you want. The path is in the form: Dataset > Data Model > Field.

Next, map the filter to the widgets that you want to control. Widgets created from the same dataset as the filter will be automatically mapped, but you can choose to toggle the mapping off if necessary.

Choose Input Type for your Filter

If the Field value for your Field Filter is either Boolean or Text, you can configure your Filter to accept a single value or multiple values by selecting Single-select List or Multi-operator Input, respectively.

Single-select List

If you choose Single-select List, your Filter can only accepts one value.

Multi-operator Input

If you choose Multi-operator Input, your Filter is able to accept a combination of multiple filter values.

Field Filters' Properties

Field filters have some neat properties:

Field Filters take on the source field's data type

For example, if the source field is of Date type, the filter will also have Date type, and so on.

A filter created from the Category field is recognized as a Text filter, and can only be mapped to Text fields

For more details on the properties of filters on each data type, please visit the individual pages.

Holistics will suggest the value of field filters based on your source field's values

If the source field is of Text type, the filter will fetch the values from the source field to give you suggestions, along with the option of entering your own values.

Holistics will fetch 100K distinct values of the filter and cache them for 8 hours

By default, Holistics will fetch the first 100K distinct values of the field and cache the result for 8 hours whenever a user clicks on the filter input box. Any permission rules for the user would be applied as well.

To refresh filter values, click on the Refresh button at the bottom of the suggestion box.

They are automatically mapped to widgets

  • If the filter is created from a field of dataset A, it will be automatically mapped to all widgets created from dataset A.
  • When you add a new widget to a dashboard, if it is also created from dataset A, the filter will also be automatically mapped to the new widget
Note
  • Since the mapping is automated, please make sure that the mapping is exactly what you need. You may want to map the filter to a different field of the widget.
  • It is not required to map the field filter to the exact same field in the widget. You can map it to any fields of the same data type.
