    2  => 25,
    3  => 85,
    4  => 23,

DESCRIPTION

Chart::Clicker::Data::Series represents a series of values to be charted.

Despite the name (keys and values) it is expected that all keys and values will be numeric. Values is pretty obvious, but it is important that keys also be numeric, as otherwise we'd have no idea how to order the data.

If you want to use text labels for your domain's see Chart::Clicker::Axis's tick_labels method.
