Customize Graphs

You can also make changes to graphs in a script. For example, create a window with a graph, get a reference to the report, and then set the frame box size.

dt = Open( "$SAMPLE_DATA/Big Class.jmp" );
biv = dt << Bivariate( Y( :weight ), X( :height ), Fit Line );
rbiv = biv << Report;
rbiv[Frame Box( 1 )] << Frame Size( 400, 400 );

To see a list of possible messages for any given display box object, select Help > Scripting Index and select Display Boxes from the list. Running the Show Properties() command is an alternative to using the Scripting Index. For example, here is a partial list of messages that you can send to an axis:

dt = Open( "$SAMPLE_DATA/Big Class.jmp" );
biv = dt << Bivariate( Y( :weight ), X( :height ), Fit Line );
rbiv = biv << Report;
Show Properties( rbiv[Axis Box( 1 )] );

Axis Settings [Action](Provides a way to bring up the axis dialog or set configurable axis options for a given axis.)

Revert Axis [Action](Restore the settings that this axis had originally.)

Add Axis Label [Action]

Remove Axis Label [Action]

...

The following expressions change the font of both axis labels (weight and height in the example above) to 12-point, italic Arial Black:

rbiv[Text Edit Box( 1 )] << Set Font( "Arial Black", 12, Italic );
rbiv[Text Edit Box( 2 )] << Set Font( "Arial Black", 12, Italic );

or

rbiv[Text Edit Box( 1 )] << Set Font( "Arial Black" );
rbiv[Text Edit Box( 1 )] << Set Font Style( "Italic" );
rbiv[Text Edit Box( 1 )] << Set Font Size( 12 );
rbiv[Text Edit Box( 1 )] << Set Font( "Arial Black" );
rbiv[Text Edit Box( 2 )] << Set Font Style( "Italic" );
rbiv[Text Edit Box( 2 )] << Set Font Size( 12 );
rbiv[Text Edit Box( 2 )] << Set Font Name( "Arial Black" ) << Set Font Size( 12 ) << Set Font Style( Italic )

The default font specified in the Preferences is applied if the font is not installed on the computer.
