While using the script I found that if the timeArr or selected time0,time1,etc menu options aren't in chronological order it will plot incorrectly so I added a sort function to automatically sort the array from lowest time value to highest keeping the corresponding colors and line thicknesses.

PHP Code:
var arrLen = null;

var lineClr = [Color.grey,Color.white,Color.aqua,Color.aqua,Color.darkgrey,Color.darkgrey,Color.navy];
var lineThick = [1,1,1,1,1,1,1];
arrLen = timeArr.length;
var x=0, y=0, i=0, j=0;
aFPArray[x] = new FunctionParameter("NumberOfLinesToDraw", FunctionParameter.NUMBER);
with(aFPArray[x++]){
setName("Draw The 1st ? Lines");//i.e., if NumberOfLinesToDraw==1 one line is drawn every time the 1st "time0" bar time is reached, if it==2 then two lines are drawn for "time0" and "time1", etc., NOTE: times and corresponding color/thickness will be automatically sorted in chronological order
