 If you now want to use your own data source you have make sure, that the data received is in the `TABLE` format and is structured as follows:
 
-* The table requires a column which is named equal to the value of the `aggregationType` settings field. This column defines the component to which the data refers to.
-**Example**: Assuming the `aggregationType` variable is set to `app`, the data table has to provide a column named `app`.
 * The table requires at least one column which specifies the connection's source or target. The settings `Source Component Column` and `Target Component Column` need to be set to the exact namings of the respective fields.
 
 * The data can contain multiple value columns. These columns have to be mapped on specifc attributes using the panel's `Data Mappings` options.

-The data mapping represents always the data from the point of view of the component which is specified by the column which name is equal to the `aggregationType` variable. This means that if we want to represent an outgoing connection in this example, the `app` and `target_app` columns must be present. In case an incoming connection should be represented, the `app` and `origin_app` columns must be present.

 In this example, we extend the data table of example 1 by another column, representing the total sum of all request response times of a specific connection (e.g. sum of all HTTP request response times).
