Legends are used to provide descriptions for the lithologic symbols, well components, and sample symbols shown in borehole logs. WinLoG comes with several previously defined legends. In addition, any number of new legends can be easily created.
Legends can be customized to display different lithologic symbol libraries, well component symbols, and sample symbols. In addition, they can include bitmaps, and paragraph text. A company logo and/or site map, stored as bitmaps, can also be included in a legend.
Although you can use an unlimited number of lithologic libraries (each with 18 symbols), only one library can be represented on the legend. If you need to show more libraries, it is recommended to create additional legends. If more symbols are specified then can be fit on the page, they will be truncated at the bottom of the page.
Each symbol also has a default symbol description stored in the library, which is used when creating legends. When a legend is created the default description will be used for the symbol description in the legend. If this description is then edited in the legend, the new description will only appear in that legend. The new description in the legend will not replace the default description in the library. To change the default description in the library, the description must be changed in the library as discussed in the next chapter. However, the actual symbols are the same in the legend as in the library and if edited in the legend the symbols in the library will change as well.
Legends are stored in the WinLoG master database. The format of the master database is Microsoft Access 2000. This database is stored in the Main Database Directory. For a detailed discussion of the database structure, see .
