A depth log with the Reverse flag set can still be selected as reference axis.
Decimal places:
Enter the number of decimals to be displayed in the depth string. Valid numbers are
0 to 5.
Horizontal Grid:
To alter the appearance of the horizontal grid lines you have to define a Spacing
first. The Spacing is measured in units set for the depth axis and is simply a
reference interval for which the frequency of major and minor grid lines as well as
the number of major/minor depth indicators (depth strings) can be set.
Spacing set to 2
Major grid line
Minor grid line
E.g. if a depth scale of 1:200 meters has been chosen with a Spacing set to 2. The
displayed spacing interval will be every 2 meters. If the depth units are changed to
feet, then the Spacing value of 2 will correspond to an interval of 2 feet.
The user can toggle the display of major and/or minor grid lines using the Major &
minor, Major, None options.
More detailed settings for major, minor grid lines and the frequency of depth marker
can be accessed when clicking the Advanced button.
Scale:
A scale of 1:100 means that the data acquired over an interval of 100 units (e.g. 100
m depth) will be displayed on 1 unit (e.g. 1 m) of paper (or screen).
Enter a new scale value into the corresponding edit box of the Depth Log Settings
dialog. If the Link scale to master depth option is enabled the actual scale settings
of the master depth axis (see: 1.4.1 Depth Axis) are applied.
If you check the Link scale to master option the depth scale is determined from
the Master Depth axis when making the Depth Log the reference axis of the
borehole document (right click on log title and choose Use As Depth Scale).
