Use

A Curve Column is used to plot quantitative data as a point-to-point curve. LogPlot offers a variety of ways to display this curve -filled, with symbols, as a block curve, etc.

How it works: As you compile your log in LogPlot, the program will locate data listed in a column in a Point Data datasheet, and will plot the data in the Curve Column of the same name. For example, data listed in a Point Data datasheet in a column named "Gamma" would plot into a curve column also named "Gamma".

Other Curve column features:

• The data 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, and style for the curve.
• The curves may be filled with a solid color if desired.
• Curves can "wrap" and can include symbols at the inflection points.
• You may include automatic value labels at regular intervals down the log.
• You can overlay any number of separate Curve Columns on top of each other - just drag them to overlie.
• You can plot specific depth intervals of a single curve at different min-max scales, with a user-defined Scale Table.
• You can request automatic min-max scaling of the column, to match the individual log's data range.

Alternatives: Columns in which two curves are displayed, with solid-fill color where they overlap are designed with the Cross Plot Curves column.

How to…

• Insert a curve column in a log design
• Set up the curve name, position, and scaling
• Set up the curve appearance
• Set up grid lines (value and depth)
• Set up automatic value labels
