Chartkick column charts multiple colors

Question

I\'m using chartckick in my RoR project to generate charts, which works quite nice. (along with Google Charts).

I\'ve created a column chart with only 2 bars

Answer 1

From @buren's comment on GitHub it seems that using a different JSON structure will invoke different colors on the column_cart.

I changed the output in the Helper:

def parse_gender_data(data)
  gender_data = Hash.new
  gender_data[:male] = data[1]
  gender_data[:female] = data[2]
  [{"name" => "Male","data" => {"Gender" => gender_data[:male]}},{"name" => "Female","data" => {"Gender" => gender_data[:female]}}]
end

And created the chartkick.rb config file (config/initializers/chartkick.rb), adding some colors:

Chartkick.options = {
  colors: ["#63b598", "#ce7d78", "#ea9e70", "#a48a9e", "#c6e1e8"]
}

Which outputs the desiring result:
