Bug: Spatially filtered data from an Oracle database cannot be used to create a box plot
Creating a box plot will fail using the result dataset from a spatial filter on data stored in an Oracle database. Spatial filters include the results of the Spatial Filter tool or the Selection tools (Select, Box select, and Lasso).
Use an attribute filter, rather than a spatial filter, if possible. For example, to filter for specific counties, use an attribute filter for the county name, rather than a spatial filter with selected counties boundaries.
