Tabulate - Add Monthly Average?

[#1]

I'm trying to add the monthly average to my tabulate table...  what am I doing wrong?  It's not averaging the price by month...

For display purposes I'm using the sample data - consumer prices.

Script:

Tabulate(
Show Chart( 1 ),
Show Shading( 1 ),
Show Control Panel( 0 ),
Set Format( Uniform Format( 10, 2 ) ),
 
Add Table(
Column Table( Grouping Columns( :Month ), Analysis Columns( :Price ) ),
Column Table( Statistics( Mean ), Analysis Columns( :Price ) ),
Row Table( Grouping Columns( :Series ) )
)
);

Result:

You're adding Mean as a Column Table in your script with the statement:

Column Table( Statistics( Mean ), Analysis Columns( :Price ) )

Instead you want to add it as an analysis column in the existing column table.

dt = Open( "$SAMPLE_DATA\Consumer Prices.jmp" );

dt << Tabulate(
	Show Chart( 1 ),
	Add Table(
		Column Table(
			Grouping Columns( :Month ),
			Analysis Columns( :Price ),
			Statistics( Sum, Mean )
		),
		Row Table( Grouping Columns( :Series ) )
	)
);

To get this syntax I built the table interactive and then asked JMP for the script from the red triangle hotspot.

Jeff,

I want to show the sum per month and the average for the year by month.

In excel I would take the average of all months.

Hi @MariaK,

One way to do what you want is to create a summary table and then run tabulate on the summary table.

dt = Open( "$SAMPLE_DATA\Consumer Prices.jmp" );

dt << Summary(
	Group( :Series, :Month ),
	Sum( :Price ),
	Freq( "None" ),
	Weight( "None" )
);

dt2 = Current Data Table();
dt2:Name("Sum(Price)")<<Set Name("Monthly Total");

dt2 << Tabulate(
	Change Item Label(
		Statistics( Mean, " " ),
		Grouping Columns( :Month( "All" ), "Monthly Average" )
	),
	Show Control Panel( 0 ),
	Set Format( Mean( :Monthly Total( 12, 2 ) ) ),
	Add Table(
		Column Table(
			Grouping Columns( :Month ),
			Add Aggregate Statistics( :Month ),
			Analysis Columns( :Monthly Total ),
			Statistics( Mean )
		),
		Row Table( Grouping Columns( :Series ) )
	)
);

Monthly Averagescheers,

Thank you Stan!  Worked like a charm. :)
