To create a data filter by managers, do the following:

1. In the Visualizations side panel, select the Slicer element ().

2. Add the Supervisor field to the filter (this will allow you to filter data by managers).

As a result, this field will be displayed in the filter.

3. Set the filter style. To do this:

• Click the style format icon ().
   

  

• Select Slicer Settings.
   

  

• In the Style settings section, select Dropdown.
   

  

• In the Selection settings section, select Multi-select.
   

  

4. Add the search function in the filter settings. To do this, click the icon and select the Search menu item.

5. In the same way, add filters for the following fields:

• Employee

• con_client

• con_spec

• con_type

• HCP Loyality

Note:
You can copy a previously created filter (Ctrl+C, Ctrl+V) — in the new filter, you will need to replace the previously added field with the required one.

The next step is to create a chart of doctor loyalty levels related to the number of contacts.
