Plot a column vs all other ones

razmah

I have a variable that shows the number of columns Y.

I want to plot x vs all Y.

for example first column is x and A=6 shows that we have 6 Y columns after x.

how to make an overlay plot?

something like:

X( :Distance ),

  Y( (:column 3) :: column (char(A))); hahaha

Thanks

If I understand correctly, something like this should do:

NamesDefaultToHere(1);

// Make some demo data

dt = NewTable("Data",

  NewColumn("y1", Numeric, Continuous, Formula(RandomNormal())),

  NewColumn("y2", Numeric, Continuous, Formula(RandomNormal())),

  NewColumn("x", Numeric, Continuous, Formula(RandomInteger(1, 20))),

  NewColumn("y3", Numeric, Continuous, Formula(RandomNormal())),

  NewColumn("y4", Numeric, Continuous, Formula(RandomNormal())),

  AddRows(10)

);

// Plot every column in dt not called 'x' against "x"

cols = dt << getColumnNames("String");

Remove From(cols, Loc(cols, "x")[1]);

dt << Overlay Plot( X( :x ), Y( Eval(cols) ), Connect Points( 1 ) );
