The area of the graph to retrieve, based on its data grid view.
A list of objects representing the data in the specified cell of the graph. For example, in a defect graph, DrillDown returns a list of Bug objects.
Areas is a two-dimensional variant array representing a list of rectangular areas in data grid. The first array dimension size must be 4.
Such an array can be logically modeled as a table with four columns where each row represents one rectangular area. Each rectangular area is a set of four coordinates: TopLeftColNum, TopLeftRowNum, BottomRightColNum, and BottomRightRowNum.
