Hello - I would like to add a background color to a JMP chart that I built in JMP Graph Builer. I save the chart as a PNG and have attached it. Does anyone know how to do this?
Go to File --> Preferences --> Styles and select the color you want:)

You should be able to go to
Edit=>Properties
and then click on the area of interest and change the background color

But for JMP 15, changing the background color of the Frame Box() using this method, does not work. It appears to have been fixed in JMP 16.
However, through scripting, you can use the
<< background color( ??? )
to get the results you want

Names Default To Here( 1 );
dt = Open( "$SAMPLE_DATA/big class.jmp" );
gb = Graph Builder(
Size( 528, 456 ),
Show Control Panel( 0 ),
Variables( X( :weight ), Y( :height ) ),
Elements(
Points( X, Y, Legend( 3 ) ),
Smoother( X, Y, Legend( 4 ) )
)
);
Report( gb )[FrameBox( 1 )] << background color( red );
and change the color
