A Cross-Plot Curves column is a specialized type of curve-plotting column, in which two curves are displayed in the same column. Distinct colors can be selected for the curves themselves, and for the region where the curves cross.

How it works: As you compile your log in LogPlot, the program will locate data listed in a column in a Point Data datasheet, flagged with the same names as the curves set up in the Cross-Plot Curves column, and plot those data values in the log. For example, data contained in Point Data datasheet columns named "NPHI" and "RHOB" would plot into Crossplot Curve columns also named "NPHI" and "RHOB".

Other Crossplot Curve column features:

• The data in each curve may be plotted from left to right or right to left, linear or logarithmic scale, with or without horizontal or vertical reference grids.
• You may vary the line color, thickness, style, and fill for the curves.
• Define a separate color for the cross fill.
• You can request automatic min-max scaling of the column, to match the individual log's data range.

Alternatives: Columns in which individual curves are displayed are designed with the Curve Column tool.

How to…

• Insert a Cross-Plot Curve Column in the log design.
• Set up the Cross-Plot Curve position and over-plot color.
• Set up the Cross-Plot Curve names, data range, scaling, and appearance.
• Set up grid lines (value and depth).
