Building Multiple Graphs from one Data Table

[#1]

When I build a graph from a dt like this:

gb = Data_Table << Graph Builder(
		Size( 534, 454 ),
		Show Control Panel( 0 ),
		Show Legend( 0 ),
		Variables( 
			X( :Split ),
			X( :Wafer, Position( 1 ) ),
			Y( As Column( analysisTests[i] ) ),
			Color( :Split ) 
		),
		Elements( 
			Points( X( 1 ), X( 2 ), Y, Legend( 21 ) ),
			Box Plot( X( 1 ), X( 2 ), Y, Legend( 22 ) ) 
		)
	);

It works great.  However, if I put it all in a loop, hoping to generate a set of graphs (one for each of the column labels) each in their own window, it just updates the first graph instead:

for(i = 1, i <= N Items(analysisTests), i++,
     gb = Data_Table << Graph Builder(
		Size( 534, 454 ),
		Show Control Panel( 0 ),
		Show Legend( 0 ),
		Variables( 
			X( :Split ),
			X( :Wafer, Position( 1 ) ),
			Y( As Column( analysisTests[i] ) ),
			Color( :Split ) 
		),
		Elements( 
			Points( X( 1 ), X( 2 ), Y, Legend( 21 ) ),
			Box Plot( X( 1 ), X( 2 ), Y, Legend( 22 ) ) 
		)
	);
);

How do I get it to show a set of graphs, each in it's own window?  It seems like because its asking for a graph based on a data table I would need multiple data tables each with it's own graph, but it seems like there should be an easier way.  I tried gb[i] hoping to get a separate graph for each loop, but that gives an error. -- Not subscriptable value in access or evaluation of 'Assign'

Hi,
One way to do this is 1) create a new window and a ListBox outside the loop, 2) Append each graph to the ListBox within the loop, and 3) Append the new window with the ListBox after the loop closes. I don't have the time to give you a complete script solution but you might be able to figure it out with the Scripting Help and Manual.
Best,

Not sure why that is - I would expect the default action to be that separate windows are created; as in this script:

dt = open("$SAMPLE_DATA/Big Class.jmp");
cols = dt << get column names;
for (i=1,i<=nitems(cols),i++,
	dt << Graph Builder(
		Size( 353, 317 ),
		Show Control Panel( 0 ),
		Variables( X( :height ), Y( eval(cols[i]) ) )
	);
)

If I misunderstood what you meant by "window" - and that what you really want are lots of graphs in a single window then you need to put the graph in a container (that prevents it being rendered immediately) and then append it to a pre-existing display box (hlb in this example)

dt = open("$SAMPLE_DATA/Big Class.jmp");
cols = dt << get column names;
NewWindow("Demo",
	hlb = HListBox()
);
for (i=1,i<=nitems(cols),i++,
	content = VListBox(
		dt << Graph Builder(
			Size( 353, 317 ),
			Show Control Panel( 0 ),
			Variables( X( :height ), Y( eval(cols[i]) ) )
		)
	);
	hlb << append(content)
);

Thanks David,

This is actually exactly what I was doing, but it was only showing the last one.  I ended up finding a bug in part of the "extra" script I didn't show and once that was fixed it started working correctly.  So you're answer showed me that I was doing it right and pointed me in the right direction to finding the real problem.  Thanks
