GoSpark

A small sparkline utility inspired by holman/spark

Pretty cool way to display small signals in a heartbeat. Here's a neat list of awesome usage ideas for spark.

import (
  "github.com/omgnuts/gospark"
)

func main() {
  series := []float64{ 67, 71, 77, 85, 95, 104, 106, 105, 100, 89, 76, 66 }
  signals := gospark.Signals(series)
  fmt.Println(signals)
}

output: "▁▂▃▄▆███▇▅▃▁"

Another mini example for stock price signals

func main() {
  prices := []float64{1398.56,1360.16,1394.46,1409.28,1409.12,1424.97,1424.37,1424.24,1441.72,1411.7,1416.83,1387.12,1389.94,1402.05,1387.67,1388.26,1346.09,1346.09,1352.17,1360.69,1353.43,1333.36,1348.05,1366.42,1379.19,1381.76,1409.17,1391.28,1355.62,1366.7,1401.69,1395.07,1383.62,1359.15,1392.15}
  signals := gospark.Signals(prices)
  fmt.Println(signals)
}

output: "▅▂▅▆▆▇▇▇█▆▇▄▅▆▅▅▁▁▂▃▂▁▂▃▄▄▆▅▂▃▆▅▄▂▅"

Works from the console too

# gospark 10 15 6 23 5 0 0 1 15 0 17 3 0 0

output: "▄▆▃█▂▁▁▁▆▁▆▂▁▁"

Ok that's all folks. Enjoy!
