Using a control with a parameter in Amazon QuickSight - Amazon QuickSight

Using a control with a parameter in Amazon QuickSight

In dashboards, parameter controls appear at the top of the data sheet, which contains a set of visuals. Providing a control allows users to choose a value to use in a predefined filter or URL action. Dashboard users can use controls to apply filtering across all visuals datasets on a dashboard, without having to create the filters themselves.

The following rules apply:

  • To create or edit a control for a parameter, make sure that the parameter exists.

  • Multiselect list controls are compatible with analysis URLs, dashboard URLs, custom actions, and custom filters. The filter must be either equal or not equal to the values provided. No other comparisons are supported.

  • Lists show up to 1,000 values. If there are more than 1,000 distinct values, a search box appears so you can filter the list. When the filtered list contains less than 1,001 values, the contents of the list appear as line items.

  • The Style option displays only the style types that are appropriate for the parameter's data type and single or multivalue setting. If the style that you want to use isn't in the list, recreate your parameter with the appropriate settings and try again.

  • If your parameter links to a dataset field, it must be an actual field. Calculated fields aren't supported.

  • The values display alphabetically in the control, unless there are more than 1,000 distinct values. Then the control displays a search box instead. Each time you search for the value you want to use, it initiates a new query. If the results contain more than 1,000 values, you can scroll through the values with pagination. Wildcard search is supported. To learn more about wildcard search, see Using wildcard search.

Use the following procedure to create or edit a control for an existing parameter.

To create or edit a control for an existing parameter

  1. Choose an existing parameter's context menu, the v icon near the parameter name, and choose Add control.

  2. Enter a name to give the new control a label. This label appears at the top of the workspace, and later at the top of the sheet that a dashboard displays on.

  3. Choose a style for the control from the following:

    • Text field

      A text field lets you type in their own value. A text field works with numbers and text (strings).

    • Text field - multiline

      A multiline text field lets you type in their own values. With this option, you can choose to separate values you enter into the parameter control by a line break, comma, pipe (|), or semicolon. A text field works with numbers and text (strings).

    • Dropdown

      A dropdown list control that you can use to select a single value. A list control works with numbers and text (strings).

    • Dropdown multiselect

      A list control that you can use to select multiple values. A list control works with numbers and text (strings).

    • List

      A list control that you can use to select a single value. A list control works with numbers and text (strings).

    • List - multiselect

      A list control that you can use to select multiple values. A list control works with numbers and text (strings).

    • Slider

      A slider lets you select a numeric value by sliding the control from one end of the bar to another. A slider works with numbers.

    • Date-picker

      Using a date-picker, you can choose a date from a calendar control. When you choose to add a date-picker control, you can customize how to format dates in the control. To do so, for Date format, enter the date format that you want using the tokens described in Customizing date formats in Amazon QuickSight.

  4. (Optional) If you choose a dropdown control, the screen expands so you can choose the values to display. You can either specify a list of values, or use a field in a dataset. Choose one of the following:

    • Specific values

      To create a list of specific values, type in one per line, with no separating spaces or commas, as shown in the following screenshot.

      In the control, the values display alphabetically, not in the order that you typed them.

    • Link to a data set field

      To link to a field, choose the dataset that contains your field, then choose the field from the list.

      If you change the default values in the parameter, choose Reset on the control to show the new values.

    The values that you choose here are unioned with the static default values in the parameter settings.

  5. (Optional) Enable the option Hide [ALL] option from the control if the parameter has a default configured. Doing this shows only the data values and removes the option to select all items in the control. If you don't configure a static default on the parameter, this option doesn't work. You can add a default after adding a control by choosing the parameter, and selecting Edit parameter.

  6. (Optional) You can limit the values displayed in the controls, so they only show values that are valid for what is selected in other controls. This is called a cascading control.

    To create one, choose Show relevant values only. Choose one or more controls that can change what displays in this control.

    When creating cascading controls, the following limitations apply.

    • Cascading controls must be tied to dataset columns from the same dataset.

    • The child control must be a dropdown or list control.

    • For parameter controls, the child control must be linked to a dataset column.

    • For filter controls, the child control must be linked to a filter (instead of showing only specific values).

    • The parent control must be one of the following.

      • A string, integer, or numeric parameter control.

      • A string filter control (EXCLUDING Top-Bottom filters).

      • A non-aggregated numeric filter control.

      • A date filter control (EXCLUDING Top-Bottom filters).

  7. When you finish choosing options for your control, choose Add.

The finished control appears at the top of the workspace. The context menu, shaped like a v, offers four options:

  • Reset restores the user's selection to its default state.

  • Refresh list applies only to drop-downs that are linked to a field in a dataset. Choosing Refresh list queries the data to check for changes. Data used in the control is cached.

  • Edit reopens the control creation screen so that you can change your settings.

  • Delete removes the control. You can recreate it by choosing the parameter context menu.

In the workspace, you can also resize and rearrange your controls. The dashboard users see them as you do, except without being able to edit or delete them.
