WellCAD Basics - Advanced Logic Technology

APPENDIX A - 271
In some cases it might be possible that different line styles appear always as solid
line or differences in line thickness (Weight) cannot be seen. One reason for this
behavior can be the settings of your graphic card, in particular the selected
resolution or optimization settings.
Shading:
Shading an Interval Log triggers WellCAD to fill the area between log border and
line with a solid color if the data display style in Bar Edge. The shading color
corresponds to the selected Pen color. From the Pos. drop down list choose
whether you want to shade the area left or right of the line. A selection of none
disables the shading.
The Type drop down list offers three different kinds of shading methods:
- Opaque: The shading color covers everything that is below. Other log data will
be covered if it is drawn before and the Overwrite Depth Grids option has
been selected. The order of drawing can be seen from the order of log titles.
The one on top is drawn first, the one at the bottom will be drawn last.
-
Log 1 is drawn first
Log 2 is drawn next
Log 3 is drawn on top
- Transparent: The shaded area appears translucent. Grid lines shine through as
well as curves. If two transparent shading colors are superimposed a third color
will be composed automatically.
- Combined: In combined shading mode the area between two curves can be
shaded. To do so, select both logs and call up the Main Settings Dialog box.
Enable shading for both logs and set the shading type to Combined. Click OK
and set a Pen color (shading color) for each of the two logs.
- Horiz. / Vert. Gradient: In horizontal gradient shading mode the area
between log border and curve will be shaded with a color determined from
current data value and selected color palette. The range of color values in the
color palette represents the range of data values between the Low and High
scale values set. Horizontal and vertical is the direction in which the color
gradient is applied.
