Simulation data must often be compared to experimental data so VisIt provides a number of features that allow quantitative information to be extracted from simulation databases. This chapter explains how to visualize derived variables created with expressions and query information about a database. This chapter also explains VisIt's Pick, Query and Lineout capabilities which allow users to compute highly sophisticated quantitative, as opposed to visual, results.
