Using Chart Portlets

Chart portlets enable you to visualize data in various types of charts. Presenting numerical data in a graphical way can help to convey valuable information at a glance. Depending on the Rochade applications you have installed, chart portlets are available for a wide range of data, including inventory data, usage statistics, and other key metrics.

These are the available chart portlets:

Chart Portlet	Description
Anomaly Metrics (Production/Development)	Displays the number of anomalies found in approved data concepts and in data concepts that are currently in process.
Big Data Governance Metrics	Displays the number of governed directories, governed Hive tables, and defective Hive tables of a selected big data cluster. The portlet is available only if a big data scanner is installed in the Rochade environment and the item types of the scanner are available in the metaApps subject area.
Chart by <column>	User-defined charts that visualize the distribution of data in selected query results or item lists. For details, see Generating User-Defined Chart Portlets.
DQ Trend Chart for <item>	User-defined charts that visualize changes in the data quality for selected items over a specific period of time. For details, see Generating DQ Trend Chart.
Events	Displays the open tasks awaiting your action and lists the key figures about workflow-related data. For details, see Using Ticker Portlets.
Inventory Data Structure	Displays the number of data structure items such as packages, files, records, domains, and data types.
Inventory ER Modeling	Displays the number of entity relationship items such as models, subject areas, entities, identifiers, attributes, and relationships.

The items for the Inventory charts described above are counted in chunks. When the counting is in progress, the chart widget displays the "Refreshing..." text message in the chart panel. This text message disappears when the counting is completed. The chart widget displays the chart after the counting is completed. You can perform other tasks while the chart preparation is in progress.
