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:
Member name | Description |
None | Raw values (no aggregation). |
Sum | Calculates the sum of all values for each point. |
Count | Number of values for each point. |
Average | Average of all values for each point. |
Minimum | Gets the minimum value for each point. |
Maximum | Gets the maximum value for each point. |
Variance | Gets the variance of the values for each point (sample). |
VariancePop | Gets the variance of the values for each point (population). |
StandardDeviation | Gets the standard deviation of the values for each point (sample). |
StandardDeviationPop | Gets the standard deviation of the values for each point (population). |
