Is it possible to change the color of a Column-Chart created with Chartkick ? I searched for it inside the Documentation but i could not find anything about it. Any Ideas?
For Google Charts, use the library option to change the color of the entire series.
<%= column_chart data, :library => {:colors => ["red"]} %>
There's not an easy way to change each bar in a single series at the moment.
