TDecisionSource Class

TDecisionSource links a decision control to a configuration (pivot state) of the data from a decision cube.

Pascal
TDecisionSource = class(TComponent);
C++
class TDecisionSource : public TComponent;

Use TDecisionSource to provide a decision grid or decision graph with cross-tabulated data from a decision cube. TDecisionSource represents a particular pivot state of dimensions from the decision cube into row and column dimensions. TDecisionSource also provides methods to drill down the display of a dimension to focus on summaries over a single value, or hide or show dimensions in the pivot state. 

All decision controls that share a decision source display the same pivot state. For example, a form could contain a decision grid and a decision graph linked to the same decision source. Pivoting the dimensions of the decision grid would automatically update the image of the graph accordingly. To display two separate projections of the information from a decision cube in a single form, use two separate decision sources. 

The pivot state of a decision source can be changed by manipulating a decision grid or by using a decision pivot.
