def self.[](make)
  self.config[make.to_sym]
end

.config ⇒ Object

Internally, this config is represented as:

config = {
  :fusion => {
    :default => :v31,
    :v3_1 => {
      :format => 'xml',
      :pie => {
        :data => 'pie.xml.builder',
        :chart_type => 'Pie2D',
        :remote => 'remote.html.erb',
        :inline => 'inline.html.erb'
      }
    }
  }
}

Internal configs can be overridden in rails environment configs. For example, to use a custom :inline ERB template (paths are based on RAILS_ROOT):

ALaChart::Config[:fusion][:v3_1][:pie][:data] = 'app/views/reports/a_la_chart/custom_inline.html.erb'

Then just copy the original template from the gem config dir, and make the desired changes
