Hi Ted
No option in 'Red triangle' or somewhere in survival platform. My solution is add customer graph.
Sample data used 'Blenders', function 'survival'. Add JSL in customerize window.(See picture).
Hope it can help to solve your problem.
Attach JSL as below.
lineAuto_x=[9000 10000];
lineAuto_y=[0.95 0.95];
Pen Color("Red");Pen Size(2);
Drag Line( lineAuto_x, lineAuto_y );
lineM_x=[9000 10000];
lineM_y=[0.88 0.88];
Pen Color("Blue");Pen Size(2);
Drag Line( lineM_x, lineM_y );
Text( {10300, 0.93}, "Automatic" );
Text( {10300, 0.86}, "Manual" );
心若止水
