new DataOperation(join_type, initiator, params)
Perform a data operation (such as a join)
Parameters:
| Name | Type | Description |
|---|---|---|
join_type |
String | |
initiator |
The entity that initiated the request for data. Usually, this is the data layer. This argument exists so that a data_operation could do things like auto-define axis labels/ color scheme in response to dynamic data. It has potential for side effects if misused, so use sparingly! |
|
params |
Optional user/layout parameters to be passed to the data function |
