In the Dashboard Designer, click the Filters tab on the left.
Under the Dimensions category, click the date
field.
Note that this adds a filter to the dashboard. This filter is based directly on the
field date, and has a type timestamp.
Add the two other filters. Under the Dimensions category, click
the category field to add a filter based on that field. Similarly, click
the pddistrict field to create the next filter.
Note that there are 39 possible options for the category filter,
and 10 options for pddistrict filter.
