Changes to chart properties when data source items are charted

Charting items from a data source might change the properties of your chart. For example, Analyst's Notebook might automatically add new entity types and attribute classes to the chart.

When you chart an item from a data source, Analyst's Notebook checks whether the item's entity type or link type, and the attribute classes of the item, exist in the chart. These checks are on the item type or attribute class name. If they do not exist, Analyst's Notebook adds them to the chart.

If the chart already contains an item type or attribute class that has the same name, then they determine the appearance of the data source item. For example, the item type in the chart specifies the icon that represents the item, and the existing attribute class might specify a prefix.

Some data sources provide the facility to choose which item types and attribute classes are used when you chart items from the data source.
