Customise the graphic log

To change the column width, position the mouse pointer on the edge of the column you want to resize. The mouse pointer will change to a two way arrow. Hold down the left mouse key and drag the mouse  to resize the column.

Using the preferences window (see figure bellow) the user can change the layout and format of the log table to suit particular needs. The preferences window can be invoked by selecting Preferences in the Tools menu; alternatively click Preferences    on the toolbar. Alternative layouts can be used, using all or some of these columns, or using some of the following additional columns.

(a) Bioturbation: this column may be used to display symbols for different types of ichnofauna plus a value to indicate the intensity of the bioturbation.
(b) Facies: a useful way of the showing the facies is to use a narrow column for each facies and filling in the column adjacent to the appropriate beds. This format of representing facies information can provide a quick, visual impression of the distribution of facies within a succession, and if the order of the columns is arranged appropriately, for example with the shallowest representation of depositional environment on the left and the deepest on the right, then shallowing or deepening trends can be recognised.
(c) Palaeocurrent data is recorded bed-by-bed with multiple entries for a single bed possible: SedLog stores the data numerically, but it can be displayed on the graphic log either as numbers of as arrows with appropriate orientations.
(d) Columns for stratigraphic information: 'Age' and 'Formation' columns are intended to be placed on the left side of the log, with boundaries between stratigraphic units entered at the appropriate bed and names displayed with text aligned vertically.
(e) Three further user-defined columns are available for entering either text or numerical data. These may be used to record features such as colour, the positions of samples or photographs or data that result from geochemical or other analyses.

Any of the columns can be renamed via a layout window (see figure bellow) and this window can also be used to modify a number of other aspects of the appearance of the graphic log. Several different scales are available, from 1:10 to 1:1000; there are also options on the intervals for display of the numbers on the scale and the scale can either measure form bottom to top for outcrop or downward for depth in borehole core. The size of the symbols, the magnification of the lithology patterns and the font sizes can be adjusted to suit different log scales. The order of the positions of the columns from left to right can be changed as required, and the name of the column customised. The default title at the top of the grain size scale is a dual clastic and carbonate scale, but either can be used on its own. The title of the log is also inserted via this window. An important consideration in the design of SedLog has been the desire to allow the user as much flexibility as possible in the appearance of the output, although there are some limitations: for example, the total number of columns available is fixed and symbols can only be inserted into some columns. The width of columns can be modified on-screen by click-and-drag of the column boundaries. Once a layout has been created it can be saved as a template for multiple data sets.
