Default Selection

The default selection feature refers to the date range that is automatically selected when the calendar is first opened or the page is refreshed. This default selection can be set to various time ranges, such as the current day, week, or month. The default selection feature can help control the initial period of data that needs to be selected based on the user's needs and preferences.

You can choose from the commonly used periods from the dropdown or create a custom selection.

Here is the list of commonly used periods:

Name	Description
Max Date	Selects the latest date available in your data.
Max Week	Select the latest week available in your data.
Max Month	Select the latest month available in your data.
Max Year	Select the latest year available in your data.

Steps to create custom default selection​

To add a custom field as the default selection, follow these steps:

1. Create a column or measure in your data.

   • Use a 0/1 condition, where 1 represents true and 0 represents false.

   • This column can be created in your source data, Power Query Editor, Calculated Column, or using DAX formula.

DAX Measure Example

VAR _date = MIN('Date'[Date])

VAR Result = 
        IF(_date = BLANK(), BLANK(), 
            SWITCH(TRUE(),
                _date = DATE(2022, 12, 10), 1,  // 1 for true dates
                _date = DATE(2022, 01, 22), 1,
                0)                              // 0 for false dates
        )
    
RETURN
Result

2. Drag the custom column into the default selection field.

   • Ensure that the column is of numeric type.

   • If it's a column, choose either MIN or MAX as the aggregation type.

3. Open the default selection option in the advanced settings.

4. Select “Based on field” from the dropdown.

5. Select the custom column.

6. Hit “Apply” to save.

The default period based on your custom field will now be applied. To test it out, clear any existing filters and refresh the page.
