You can easily add notations to your graph that will not move, by using the "Customize" capability.
The notation was added interactively. Below is the resulting script for the chart....
Note: The Big Class sample data table was used for my example
Graph Builder(
Variables( X( :weight ), Y( :height ) ),
Elements( Points( X, Y, Legend( 3 ) ), Smoother( X, Y, Legend( 4 ) ) ),
SendToReport(
Dispatch(
{},
"weight",
ScaleBox,
{Min( 60 ), Max( 182.231404958678 ), Inc( 20 ), Minor Ticks( 0 )}
),
Dispatch(
{},
"height",
ScaleBox,
{Min( 50 ), Max( 75.140306122449 ), Inc( 5 ), Minor Ticks( 1 )}
),
Dispatch(
{},
"Graph Builder",
FrameBox,
{Add Graphics Script(
2,
Description( "Script" ),
myList = {};
Insert Into( myList, X Origin() + .2 * X Range() );
Insert Into( myLIst, Y Origin() + .8 * Y Range() );
Text( Center Justified, myList, "Here is a note" );
), Grid Line Order( 1 ), Reference Line Order( 3 )}
)
)
);
