Hi @ivanpicchi ,
It seems that there is no GUI to change the blue line of logworth. You have to use a script to change the line.
Here is an example.
//Calculate logworth from alpha
alpha_level = 0.07;
logworth_values = -Log10( alpha_level );
//Get a reference for the report
rpt = Current Report();
value_matrix = rpt[Outline Box( "Effect Summary" )][Plot Col Box( 1 )] << get as matrix;
count_n = N Row( value_matrix );
line_value = J( count_n, 1, logworth_values );
//Change the line
rpt[Outline Box( "Effect Summary" )][Plot Col Box( 1 )] << lower( line_value );
rpt[Outline Box( "Effect Summary" )][Plot Col Box( 1 )] << upper( line_value );
Hope it helps.
