In EnviroInsite, the term Stratigraphy is used to refer to the regional geologic or hydrogeologic units that are likely to be continuous between boreholes. In order to impose some consistency on the hatch patterns used to represent particular units between different plots, the stratigraphy hatch patterns are set at the document level. In order to set the hatch patterns, select Edit-> Format->Stratigraphy . Note that for each unit, you may select two hatch patterns. If anything other than SOLID is selected for Fill Style 1, then the final printed hatch pattern will be the combination of the Fill Style 1 and Fill Style 2 hatch patterns.
