Log display GeoColumn tab

 

The GeoColumn tab provides options for displaying a curve using "geocolumn" shading. The GeoColumn feature shades a curve with multiple colors based on curve values. It's like cutoff shading but using many cutoffs.

Shading Direction

Sets the direction of the shading.  The shading can be to the left or right of the log curve.

Log Used For Shading

Values from the curve selected here are used to define the color "cutoff" ranges. This curve can be the same curve as being shaded or can be any other curve.

GeoColumn Base Line Value

Shading occurs from the curve traces back to either the track edge or a specified curve value.

Use Discriminator

A discriminator curve is a "flag" curve containing 1's and 0's. When a discriminator curve is used, the GeoColumn shading will occur only where the discriminator curve is equal to 1.

Use Discriminator

Enables the Discrim tab, which establishes a discriminator curve.  A discriminator curve suppresses geocolumn shading at depths where the curve has a has a value of 0 or NULL.

Suppress Curve Outline

The curve trace is not drawn. Only the shading will be drawn.

Transparent When Background Color

When the shading color matches the screen background color, shading will not occur.
