class Gruff::SideBar

Graph with individual horizontal bars instead of vertical bars.

Here’s how to set up a Gruff::SideBar.

g = Gruff::SideBar.new
g.title = 'SideBar Graph'
g.labels = {
  0 => '5/6',
  1 => '5/15',
  2 => '5/24',
  3 => '5/30',
}
g.group_spacing = 20
g.data :Art, [0, 5, 8, 15]
g.data :Philosophy, [10, 3, 2, 8]
g.data :Science, [2, 15, 8, 11]
g.write('sidebar.png')
