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 1.05 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 2.0 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:
İPlot data from a spreadsheet that contains events for both sections.
İOpen 2 individual files containing event data to find and plot the events common to both wells.
İEach data file may have up to 3000 events (limit may be increased on request).

Features:
İAutomatically find and cross-plot events common to any 2 sections.
İAuto-rescaling of chart by re-sizing window
İVariable symbol size
İVariable font and font size
İSelect from all available fonts
İReverse direction of X-axis
İDraw line of correlation-LOC
  -hold shift key down and click end points for each line segment of the LOC
İUndo LOC line segments with Undo or Clear entire LOC with Clear (Edit menu)
İSet new minimum axis values
  -click or drag mouse with option key down
İRe-set minimum axis values to data range
  -select Reset Min values from Options menu
İInteractive 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):
İPICT is compatible with nearly every Macintosh application and many Windows applications.
İCharts are fully editable with any drawing application.
İElements of the chart are grouped for easy editing with graphics applications.
İEasily 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 2.0 to find FAD and LAD events and error ranges from spreadsheets of occurrence data.

    Price: $150 US retail.
