12. Multiple Databases and Windows

In this chapter, we discuss how to use VisIt to visualize multiple databases using either a single window or multiple visualization windows that have been locked together. After a general discussion of databases, we move to database correlation, which is used to relate multiple time-varying databases together in some fashion. The use of database correlations will be explained in detail followed by a description of database comparisons, then common useful operations involving multiple visualization windows.
