This example shows how a horizontal line might be used to show the total depth on a shallow borehole log.

How to enter the Horizontal Line Data
Use: The LogPlot Horizontal Line tab is used to enter one or more depth levels at which a horizontal line is to be plotted across a portion of the log, or across the entire log, as set up in the log design. This is often used to create a solid line at the lowest depth in the log. If a second, unequal depth is specified in this tab, then the line will be plotted at an angle between the two depths. You may specify a line style, color, and thickness for each line, or you can let the lines default to the format established in the log design.
! In the log design, you can request that the horizontal line be plotted at regular depth increments, in addition to the manually-declared depths done here. If you want the lines plotted at regular intervals only, you need not create a data tab.
Corresponding log design component: Horizontal line depths declared in this datasheet will be plotted on the log in the Horizontal Line column of the same name.
Corresponding RockWorks data table: none
Right-Click Options: When you right-click in any of the Horizontal Line tab's cells, you have the following options:
Cut, Copy, Paste Insert/Append/Delete Rows Manipulate Columns Fill Depth Column Edit Data Page Name Delete Data Page Move
This example shows how a horizontal line might be used to show the total depth on a shallow borehole log.
Automatic:
If there is already a Horizontal Line item in the current log design to which you will be linking the data, you can use the Data | Update Data File from Log Design menu option to insert a new Horizontal Line datasheet in the current data file. The program will know how to name the tab based on the log design information.
Manual:
Select the Data | New Data Page | Horizontal Line menu option to insert a Horizontal Line datasheet manually.
New Name: Type in a name for the datasheet. The name must match character-for-character the name of the Horizontal Line in the log design. (The match is not case-sensitive.)
Click OK.
The program will add to the data file a Horizontal Line datasheet labeled with the selected name.
Left: Here you enter the depth at which the horizontal line or lines is/are to be plotted. If, for example, you wanted a single horizontal line plotted at the final depth of your log, you would type in that depth here.
Right: Optional. If this column is left blank, the program will assume the line is to be plotted horizontally at the depth declared in the Left Depth column. If, however, you want the line plotted at an angle between two depths, you can enter the depth for the right side of the line here.
Line: Optional. Double-click in this cell if you want to choose a line style, color, and thickness for the horizontal line. If you leave this cell blank, LogPlot will plot the line using the settings defined in the log design.
Note that the horizontal placement of the line(s) is determined by the placement of the Horizontal Line Column in the design screen.
