Add filters to your map to limit the data that is displayed. Filters must be based on the columns in your dataset.
To add a filter:
Select Filters from the right navigation bar. ​
The Filters panel displays the list of existing filters, color-coded by dataset. To create a new filter, Click Add Filter.
Choose a dataset, and then a field on which to filter your data. Filter values are defined by field data type (number, string, timestamp, etc.). ​
Your filter is applied to your map as soon as you specify the field and value.
Delete a filter anytime by clicking the trashcan to the right of the filter you wish to delete.
Note: filters apply to all layers in the same dataset on your map.
