Graphic correlation of event data from 2 sections

This application finds the common events in any 2 sections and plots bivariate graphic correlation diagrams.
(after Shaw, 1964).

ShawPlot 1.07 plots graphic correlation of event data from 2 wells.
Diagrams may be saved as PICT files for inclusion into larger montages.

Instructions:
Open a tab-delimited ASCII TEXT file that contains the data.
The data must be organized into at least two columns as follows:

Individual event files:
Event*rank¶
  or
Event*rank*rankError¶

Files with combined events from 2 sections:
Event*Top1*Top1Err*Base1*Base1Err*Top2*Top2Err*Base2*Base2Err¶

1) The first column must contain the event name or id number values.
2) Events should be positive values (depths, ranks, etc.).

Use WellPlot 4 for Max OS X to generate event data.
Use RC-RASC 1.0 to generate a scaled optimum sequence of events from multiple sections.
Use the scaled optimum sequence as a reference section in ShawPlot.

Functions:
• Plot data from a spreadsheet that contains events for both sections.
• Open 2 individual files containing event data to find and plot the events common to both wells.
• Each data file may have up to 3000 events (limit may be increased on request).

Features:
•Automatically find and cross-plot events common to any 2 sections.
• Auto-rescaling of chart by re-sizing window
• Variable symbol size
• Variable font and font size
• Select from all available fonts
• Reverse direction of X-axis
• Draw line of correlation-LOC
  -hold shift key down and click end points for each line segment of the LOC
• Undo LOC line segments with Undo or Clear entire LOC with Clear (Edit menu)
• Set new minimum axis values
  -click or drag mouse with option key down
• Re-set minimum axis values to data range
  -select Reset Min values from Options menu
• Interactive display of coordinates
  -hold mouse button down and x-y  coordinates will display in upper left of screen

Save charts as PICT file (or copy to clipboard):
• PICT is compatible with nearly every Macintosh application and Windows application.
• Charts are fully editable with any drawing application.
• Elements of the chart are grouped for easy editing with graphics applications.
• Easily create montages in Canvas, MacDraw or your favorite graphics application.

Save common FAD and LAD events:
Event*Top1*Top1Err*Base1*Base1Err*Top2*Top2Err*Base2*Base2Err¶

Data input:
ShawPlot 1.0 reads events from tab-delimited ASCII spreadsheets.

  • It accepts a single spreadsheet with common events and errors for 2 sections, or
  • It reads 2 separate files containing event data for each section and finds the events common to both sections.
  • The resulting common events may be saved to a single file.
  • Data acquisition:
    Use WellPlot 4 for Mac OS X to find FAD and LAD events and error ranges from spreadsheets of occurrence data.

    Price: $150 US retail.
