The Matrix view provides a more global view of your result data, in contrast to the Tabular view. Placing various attributes of your data on each axis provides numerous ways to shape your data. You can quickly look across your entire data set or use filters to selectively pare down your results.
Once you have assigned, and optionally sorted, axis attributes, choose a measure using the display attribute drop-down. Further limit values by using a threshold that applies to your chosen display attribute.
As elsewhere, the histogram button will allow for further analysis and paring down of your data set.
By choosing "Interactive" as the Navigate option, double-clicking individual data points in the matrix will pull up the tabular view of that data.
