<lang groovy>def sparkline(List<Number> list) {

def (min, max) = [list.min(), list.max()]

def div = (max - min) / 7

list.collect { (char)(0x2581 + (it-min) * div) }.join()

}

def sparkline(String text) { sparkline(text.split(/[ ,]+/).collect { it as Double }) }</lang>

Test Code

<lang groovy>["1 2 3 4 5 6 7 8 7 6 5 4 3 2 1", "1.5, 0.5 3.5, 2.5 5.5, 4.5 7.5, 6.5"].each { dataset ->

println " Dataset: $dataset"

println "Sparkline: ${sparkline(dataset)}"

}</lang>

Output

{{out}}
