Composited Fields

To access this screen:

In the Tables window, right-click and select Format.
In the Columns in View window, click Add.

The Composited fields screen, part of the Column Wizard, is used to create a new composited data field based on a selected data column, and defines how the compositing calculation is performed.

Note: This screen is only shown if the field (or fields) selected in the Select Fields screen of the ColumnWizard can be composited.

To create a composited column in a table view:

In the Tables window, load an assays table.
Open the Table view by selecting View >> Data Tables from the menu.

Select a log table. With the table loaded, right-click the table and select Format.
Insert a new column into the table by selecting Format >> Columns and clicking Add.
On the (table) screen, select the Columns tab, and click Add.
In the Column Wizard, choose to add a Data Column and click Next.
Select an assay column, and click Next.
Choose one of the compositing methods - normally length weighted for assay results (default).
- General: compute weighted average or dominant text depending on field type (numeric or text).
- Weighted average: compute weighted average of numeric values.
- Dominant text value: compute the dominant text value in the composite.
Select a compositing Weighting Method from one of the following options:
- Length: weight values by length of sample.
- Length x SG: weight values by the length x Specific Gravity of samples. If the Specific Gravity value of any sample in the composite is absent, the weighting method for that composite will revert to length weighting.
Select Filled histogram as the display style, and select End.
On the (table) screen, click Apply.
A new column (or columns) is displayed in the table - the prefix "Comp" is used to denote that it is a composited data column, for example:
