The MultiDimensionalData object is used to hold hierarchical data displayed within the dashboard item in a unified way. The dimension value corresponding to a specific hierarchy level is stored in the AxisPoint class that defines a point in a multidimensional space. Such points are placed on a specific data axis that represented by the DataAxis class. For instance, the pivot grid has the "Row" and "Column" axes, the chart has the "Argument" and "Series" axes, etc. The DashboardDataAxisNames class provides access to names that allow you to identify various types of data axes.
