Lertap's main options are set in the System worksheet of the Lertap5.xlsm workbook.

 

SystemWorksheetPartial3Sep09

 

The options which pertain to Ibreaks and IbreaksMH reports are seen here in rows 47 to 55.  (The respective System row numbers may change over time as other options are added.)

 

Ibreaks attempts to determine the optimal size for its charts.  However, you can set your own by using the settings in rows 47, 48, and 49.

 

Rows 51 and 52 determine when Excel will use colours to highlight the sig and eta2 values in Ibreaks charts.  Row 54 does likewise for the MH Chi sq prob cell in an IbreaksMH table.

 

Row 53 turns Yates' chi -square continuity correction on or off.  In this snapshot it's set to No, which means Off.

 

Row 55's option is presently ineffective; Lertap doesn't use it.  If scores of zero are encountered, they're converted to a score of one automatically.  If this is done, Lertap will display an informative message.

 

Printing

 

The January 2015 release of version 5.10.5 was the first to introduce System settings which provide for some control over page margins and the page breaks inserted whenever Excel's print options are used.

 

More about this is found towards the end of the pdf file available here (see the heading "Ibreaks charts have not been left out" on page 14).
