I have the following snippet of JSL that checks the My_Graphs list to determine whether the ith row is a number or not and do one of two things (col 6 consists of numbers and "."). The first part of the IF works - it sets the chart min at 1.2 the LCL and draws the plot. However, if the LCL is "." it does not set the LCL to 0. Immediately below is the the first 6 rows of col 6.

0.25
-2
-0.018
.
0.25
if(Is Number(num(My_Graphs [6][i])),
(Plot << dispatch(
{"Variability Chart for..."},
"2",
ScaleBox,
{Min(num(My_Graphs [6][i]) * 1.2 ),
Add Ref Line( num(My_Graphs [6][i]), Dotted, "Red", "LCL = " || My_Graphs [6][i] , 2 ),
Show Major Grid( 1 )})
),
(Plot << dispatch(
{"Variability Chart for..."},
"2", ScaleBox, {Min(0)})
)
);//end if
