将作为列名的变量传递给可变性图表YX

你好，
我有一个堆叠数据，其列是这样的名称：
标签数据，标签2数据2，标签3数据3 ... 标签N数据N.
我试图强制每一个变异图表标签 ＆ 它的数据通过for循环。但我的问题是如何将更改的var（即列的名称）传递给Y和X. 
这是我的代码的一部分： 

 

ColList = dt << get column names( string, numeric );
show(ColList);
dt << Stack(
 columns(
  ColList
 ),
 Source Label Column( "Label" ),
 Stacked Data Column( "Data" ),
 Number of Series( 3 ),
 Contiguous
);

For(k=1,k<=Length(test_list),k++,
 Variability Chart(
 Y( :Data ), //<<<<<<---------------------Here I try TODO something like Y(:(test_list[k]))...
 X( :Label ),//<<<<<<---------------------Here I try TODO something like X(:(test_list[k]))...<BR /><BR />Max Iter( 100 ), Conv Limit( 0.00000001 ), Number Integration Abscissas( 128 ), Number Function Evals( 65536 ), Analysis Type( Name( "Choose best analysis (EMS REML Bayesian)" ) ), Connect Cell Means( 1 ), Std Dev Chart( 0 ), Points Jittered( 1 ), AIAG Labels( 0 ) ) );test_list ={test1, test2, test3};<BR />

 

 

Re：将作为列名的变量传递给可变性图表YX

您所要做的就是为每个迭代生成所需的列名。  请参阅下面的代码，了解执行此操作的一种方法：

test_list = {test1, test2, test3};
ColList = dt << get column names( string, numeric );
Show( ColList );
dt << Stack(
 columns( ColList ),
 Source Label Column( "Label" ),
 Stacked Data Column( "Data" ),
 Number of Series( 3 ),
 Contiguous
);

For( k = 1, k <= Length( test_list ), k++,
 If( k = 1, countVar = "", countVar = char( k ) );
 Variability Chart(
  Y( As Column( "Data" || countVar ), //<<<<<<---------------------Here I try TODO something like Y(:(test_list[k]))...
  X( As Column( "Label" || countVar ), //<<<<<<---------------------Here I try TODO something like X(:(test_list[k]))...
  Max Iter( 100 ),
  Conv Limit( 0.00000001 ),
  Number Integration Abscissas( 128 ),
  Number Function Evals( 65536 ),
  Analysis Type(
   Name( "Choose best analysis (EMS REML Bayesian)" )
  ),
  Connect Cell Means( 1 ),
  Std Dev Chart( 0 ),
  Points Jittered( 1 ),
  AIAG Labels( 0 )
 )
);
