我正在尝试编写一个 jsl 来绘制 x 与 y 之间的双变量图，按“b”列中的值分组并在每个组中拟合一条线（来自“b”列中的唯一值）。 从我所做的手动双变量图生成的脚本如下，但我无法弄清楚如何为所有通过“b”列中的唯一值的“Fit Where”命令添加 for 循环
Bivariate(
Y( :Name( "y" ) ),
X( :Name( "x" ) ),
Automatic Recalc( 1 ),
Fit Where( :p</img> == "grpA", Fit Line( {Line Color( {228, 26, 28} )} ) ),
Fit Where(
:p</img> == "grpB",
Fit Line( {Line Color( {55, 126, 184} )} )
),
Fit Where(
:p</img> == "grpC",
Fit Line( {Line Color( {77, 175, 74} )} )
),
Fit Where(
:p</img> == "grpD",
Fit Line( {Line Color( {152, 78, 163} )} )
),
Fit Where(
:p</img> == "grpE",
Fit Line( {Line Color( {255, 127, 0} )} )
),
Fit Where(
:p</img> == "grpF",
Fit Line( {Line Color( {166, 86, 40} )} )
),
Where( :c == "TT" & :e == "EE" ),
