Reusing fonts, font styles and sizes

Is there any way to reuse font styles?

Let's say I have many graphs and for each Axis Box I apply this:

Dispatch( {}, "X", ScaleBox, {Format( "Best", 12 ), Min( 0.5 ), Max( 0.6 ), Inc( 0.0005 ), Minor Ticks( 1 ), Label Row(
    {Set Font( "Agency FB" ), Set Font Size( 8 )}
   )} )

Then I decide that size 8 is too small and now I have to go to each place I put it in and change it.

 

Any way to say something like:

myFontStyle = {Set Font( "Agency FB" ), Set Font Size( 8 )};

and then just use:

Label Row(myFontStyle)

I suspect you could do that with Expression Evaluation somehow - but I just do not comprehend this whole deal with Expressions and evaluations. Any suggestions?

Instead of using Dispatch it is often recommended to send messages to the scale boxes directly.  You can search for them and then send a list of instructions to a list of objects to make all the changes at once.  See this example:

 

names default to here(1);

dt = Open("$Sample_Data/Big Class.jmp");

gb = dt << Graph Builder(
 Size( 321, 1012 ),
 Show Control Panel( 0 ),
 Variables( X( :height ), Y( :weight ), Page( :age ) ),
 Elements( Points( X, Y, Legend( 22 ) ), Smoother( X, Y, Legend( 23 ) ) )
);

//use this to find charID:
gb << Get XML;

//Modify X Axes by first getting a list of scale boxes and then sending
//a list of messages to each.
(gb << XPath( "//ScaleBox[@charID='height']" )) << {
 Format( "Best", 12 ), 
 Min( 50 ),
 Max( 75 ), 
 Inc( 5 ), 
 Minor Ticks( 1 ),
 Label Row( {
  Set Font( "Agency FB" ), 
  Set Font Size( 8 )
 } )
};

//Modify Y Axes:
(gb << XPath( "//ScaleBox[@charID='weight']" )) << {
 Format( "Best", 12 ), 
 Min( 50 ),
 Max( 150 ), 
 Inc( 25 ), 
 Minor Ticks( 1 ),
 Label Row( {
  Set Font( "Agency FB" ), 
  Set Font Size( 8 )
 } )
};
