How to change the color of a Column-chart created with Chartkick?

问题

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?

回答1:

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.

I think it might work like this:

  = column_chart(@data, library => { :series => { 0 => { color: "red" } }

Like this you can define that for each series.
