Overview

See also the Spider graph.

Here’s how to make a Gruff::Net.

g = Gruff::Net.new
g.title = "Net Graph"
g.labels = {
  0 => '5/6',
  1 => '5/15',
  2 => '5/24',
  3 => '5/30',
  4 => '6/4',
  5 => '6/12',
  6 => '6/21',
  7 => '6/28'
}
g.line_width = 3
g.dot_radius = 4
g.data :Jimmy, [25, 36, 86, 39, 25, 31, 79, 88]
g.data :Julie, [22, 29, 35, 38, 36, 40, 46, 57]
g.write("net.png")
