Filter in a dashboard
You use filters to gain a better understanding of the information. A dashboard is usually generic and shows, for example, all of the information about turnover, actual costing, absence, etc. Use a filter to gain a better understanding of the information, for example to display only the turnover in a certain region, the actual costing of open projects or the absence in a specific department.
The beauty of filters in dashboards: if you apply a filter to one visualisation, it is applied to all visualisations on all pages of the dashboard.
You can filter data in various ways: using the filter fields in the filter bar or by clicking in the visualisations. This last method is the most intuitive one: you click on a value by which you want to filter and the filter is applied immediately.
