Limiting Date Filters to Datasource Date Range
By default, Sisense allows users to select any date in a dashboard date dimension filter, regardless of whether data exists for that date in the current dashboard datasource. The native Sisense date filter selection UI highlights the earliest and latest dates available via shading and color indications, but if a user selects a date outside this range, it is accepted as the desired filter from the user. While this behavior is generally the preferred behavior, there are cases where a dashboard creator might prefer the date filter to visually and programmatically reflect only the dates for which data exists in the datasource.
In scenarios where the exact number of days in the filter range the data being viewed from is vital, such as when analyzing total date data coverage, performing per-day calculations, or simply ensuring that the visual filter UI accurately represents the actual data period being shown, the date filter should ideally be modified to only display date ranges that have corresponding data. This ensures that the filter not only serves as a control mechanism but also as an accurate visual cue of the available data's temporal range.
The dashboard script presented below adds this custom functionality. It works by executing two custom JAQL queries (More documentation on custom script JAQL queries is available here) to fetch the sequentially earliest and latest dates from the datasource. These dates are then used as the bounds to restrict the filter. The dimensions used to fetch the date range and the dimension used to find the matching dashboard filter can be separate or identical dimensions, as they are separated in two variables. The script supports both common date filter formats, traditional "from-to" date ranges and filters that use a list of date members. Additionally, the approach can be extended to accommodate other filter types or JavaScript based actions beyond or not including filter modification when a filter's value falls outside the desired range. For more detail and an addition example see the article Redirect Users to Different Dashboards Based on Dashboard Filters.
When a user selects a date that falls outside the available range of the datasource, the code below automatically adjusts the filter. It modifies the selection so that the filter is constrained to the earliest available date if the selected date is too early, or to the latest available date if it exceeds the maximum. If both boundaries are affected, the filter is adjusted on both ends to ensure that only dates with corresponding data are displayed.
This solution provides a robust method to visually align your dashboard’s date filter with the actual data available, ensuring that users have a clear and accurate reference of the data period being analyzed. The full code implementing this functionality is provided below.
