First we flush the stack (make it empty), then we use Stack Dat$ to parse the dat$ (also empty the string). Last we rtuern an array using array() using as argument a stack object.

This solution makes use of SenseTalk's "word" chunks, in this case delimited by any number of spaces and/or commas, to simplify parsing the input string. Also note the use of the <code>but no more than</code> operator to handle the edge case where a number equal to the top value would otherwise refer to the 9th symbol, which doesn't exist.
<syntaxhighlight lang="sensetalk">put sparklineGraph of "1 2 3 4 5 6 7 8 7 6 5 4 3 2 1"
put sparklineGraph of "1.5, 0.5 3.5, 2.5 5.5, 4.5 7.5, 6.5"
put sparklineGraph of "0, 1, 19, 20"
put sparklineGraph of "0, 999, 4000, 4999, 7000, 7999"
to handle sparklineGraph of input
put each word delimited by " ," of input into numbers
put the lowestValue of numbers into bottom
put the highestValue of numbers into top
put top - bottom into range -- total range of values
put range/8 into step -- the size of each incremental step in the graph
repeat with each number in numbers
put (trunc((number - bottom) / step) + 1) but no more than 8 into symbolNum
put character symbolNum of "▁▂▃▄▅▆▇█" after graph
end repeat
put !" (range: [[bottom]] to [[top]])" after graph
return graph
end sparklineGraph
