Crossplots and Multi-well Crossplots allow the PowerLog® user to display and edit log data through a user-friendly interface. As changes are made, they are immediately reflected in the crossplot and all other viewers and processors. Changes made elsewhere are also automatically updated in the crossplot. Crossplots can display related histograms in the same graphical space.

With the overlay tool you can define templates that then overlay the crossplot. Use this tool to draw lines, post equations, create text boxes and otherwise annotate the template. For example, you can define a template of minerals and then overlay your log data to compare the data to known mineral values.

All crossplots include the following:

X, Y, and Z (color) for any three curves
Cell or scatter plot
Discriminate on unwanted data
Up to 5th order polynomial regression and RMA for selected area
One or two point normalization for X and/or Y axes
One of two interval plot
A report with pertinent information such as regression line equations
Auto-scaling with multi-well
Optional display of histograms on the crossplot
Full Windows color palette support

The following types of crossplots are available:

Generic	Neutron-Density	Neutron-Sonic
Sonic-Density	Pickett	Multi-Well
