I'm trying to create an optional argument that if it's not passed, a
default value will be assigned.
def graph (graph_type, graph_period, *hidden)
hidden = 1 if hidden.nil
1. hidden is a tinyint (0 or 1), * is used for hash, so what's the best
syntex that I should have here?
2. hidden.nil doesn't seem to work, as it's not assigning the hidden =
1. any suggestions on what I should do here?
Thanks in advance.
