How to loop generate graph for all columns

[#1]

 Hi, Everyone

I trying to get my first loop work, but stuck with one issue.

It simply gets all cloumns, and loop through and plot all columns.  The problem is in

   test ==  ( y_cols[i] ) ;

My intension is test is the individual columns name,  but when i debug, it seems test is a list of all columns, same as the y_cols.

So when i run the script, it plots only the first column, many times.

 dt = Current Data Table();

 y_cols = dt << get column names(string);

Remove From(y_cols,1,2);

nw2 = new window("My first report");

for(i=1, i <=nitems(y_cols), i++,

   test ==  ( y_cols[i] ) ;

       gb=expr(Graph Builder(

             Size( 700,250 ),

             Show Control Panel( 0 ),

             Variables(

                    X( :Part id ),

                  Y( eval(test) ),

                    Overlay( :Time )

             ),

             Elements(

                    Points( X, Y, Legend( 12 ) ),

                    Line( X, Y, Legend( 14 ), Summary Statistic( "Median" ) )

             ),

             SendToReport(

                    Dispatch(

                          { },

                          "400",

                          ScaleBox,

                          {Legend Model(

                                 12,

                                 Base( 0, 14, 0 ),

                                 Base( 1, 14, 1 ),

                                 Base( 2, 14, 2 )

                          )}

                    )

             )

       )

       );

       nw2 << append(gb);

 );

Here is a minor rework of your code to get the script to work.  The first part of the script just creqates a simple example data table.

Names Default to Here( 1 );
dt = New Table( "Test of Bivariate",
	Add Rows( 30 ),
	New Column(
		["en" => "NPN1", "ja" => "NPN1", "x-id" => "S_NPN1_Col", "zh-CN" => "NPN1"],
		Numeric,
		"Continuous",
		Format( "Best", 10 ),
		Set Property(
			"Spec Limits",
			{LSL( 104.412948990151 ), USL( 131.893493064355 ),
			Target( 118.153221027253 ), Show Limits( 1 )}

Thank you. Jim.  That worked.
