Data Aggregation

Data aggregation can be used on the entire C1Chart control through the Aggregate property or used on individual series through the Aggregate property.

Data aggregation is when data is gathered and is reflected in a summary form. Commonly, aggregation is used to collect more information about specific groups based on certain variables such as geographic location, income, and age.

C1Chart enables you to use aggregate functions for a grouped data by specifying it when the DataSeries is created. For each DataSeries you can choose from one of the following functions using the Aggregate enumeration:
