1. A computer-implemented method of operating on records of a dimensionally-modeled fact collection, comprising: receiving a graphical selection of a subset of data points from a set of displayed data points, each displayed data point representing at least one record of a dimensionally-modeled fact collection by being graphically displayed relative to at least two axes of a display, each axis of the display representing a particular dimension, and each data point representing the at least one record such that the position of the data point relative to each axis is indicative of the value of the at least one record at the dimension represented by said each axis; and exporting information associated with the selected subset of data points, wherein exporting information associated with the selected subset of data points comprises: in conjunction with the graphical selection of a subset of data points from a set of displayed data points, receiving an aggregation specification; aggregating a subset of records corresponding to the selected subset of data points in accordance with the aggregation specification; and exporting the subset of records in aggregated form.
