Panels
                                        
The following main panels are covered in this section of the Help:
- Drop Zones: used to construct queries, by placing the required hierarchies and elements in the relevant drop zones.
 - Metadata Trees
                                            
- Dimensions: consists of the data model's dimensions, which contain the model's hierarchies.
 - Elements: a hierarchy's elements tree may be opened to add only specified elements to the query, rather than the entire hierarchy.
 - Measures: the measures in the data model are organized into folders in the Measures tree.
 
 - Visualizations: the visualization menus and toolbox offers a large selection of core data visualizations to choose from.
 - Existing Content Tree: used to open existing data discoveries in a new tab.
 - Formatting Panel: used to set formatting preferences for visualizations, legends, and slicers.
 
Other mini panels in Discover exist to expose other information:
- Metadata Info: displays information and statistics about the current query and the data source.
 - Performance Dialog: displays benchmark information about the performance of the current query.
