Data source items that match chart items

If your chart already contains the data source item that you are charting, Analyst's Notebook can update the existing chart item. If your chart contains items that originate from other sources and represent the same real world object or relationship as the item that you are charting, you can merge the items to consolidate the multi-source data.

When a chart contains items from different data sources, your analysis might uncover potential duplicate data. For example, the top two people in a list of social network analysis results might originate from different data sources and have different names, but match on other key characteristics. To merge the entities, select them on the charting surface, click the Analyze tab, then click Merge and Combine > Merge Entities. You can also use the Find Matching Entities feature to detect duplicate entities.
