Hi!
I am playing with unicode characters:
-=-=-=-=-=-=-=-=-=-=-=-= Gofer new url: 'http://smalltalkhub.com/mc/abergel/Sparkline/main'; addPackage: 'Sparkline'; load. -=-=-=-=-=-=-=-=-=-=-=-=
#( 1 2 3 4) spark => '▁▃▅▇’ #(-5 10 0) spark => '▁█▃' RxsNode withAllSubclasses spark: #numberOfMethods => '▂▃▂▃▁▁▅█▁▁▂▁’
I got the inspiration from https://github.com/holman/spark
By the way, I would love to have a short tutorial about unicode characters at esug.
Cheers, Alexandre
