The Shifted Curve style divides the log track into equal intervals and draws all data
columns as individual curves using the left border of each interval as zero baseline.
Shifted Curve Data Display
All data columns are drawn as superimposed curves if the Stacked Curve style has
been set.
Shifted Curve Data Display
Reference:
Usually the left hand side of the log track is used as reference for the data (e.g. 0°,
High Side or North) and is the position of the first data point. To reverse the data
display and have the reference on the opposite track border, check the Reverse
option.
E.g. an acoustic scanner tool scans the inside of the borehole wall. The Image Log
displays the data starting with 0° on the left. The data is presented as if seen from
the inside of the hole. A core scanner image would display the data as if seen from
the outside of the hole if the left track border would be used as reference, too. To
