Rails Chartkick Gem Error Loading Chart No Adapter Found

Question

I have a Rails 3.2.14 app where I'm using the chartkick and groupdate gem to try to generate some basic charts.

When I load my view I get the error: Error Loading Chart: No adapter found

Here's what my view code looks like:

index.html.erb

<%= line_chart Call.group_by_week(:created_at).count %>

Here's my application layout including chartkick and yielding chart_js application.html.erb (layout)

 <%= javascript_include_tag "application", "chartkick" %>
 <%= yield :charts_js %>

Can anyone tell me why I'm getting this error and how to fix it? I'd really like to start using Chartkick to generate some simple charts.

Answer 1

Probably you missed loading Google Charts or Highcharts (the adapters).

Try adding this line <%= javascript_include_tag "//www.google.com/jsapi" %> before <%= javascript_include_tag "application", "chartkick" %>. Also check the Installation section in gem's home page (scroll down :)).

Answer 2

To View: Google Charts In your layout or views, add:

<%= javascript_include_tag "https://www.gstatic.com/charts/loader.js" %>

link: https://chartkick.com/#google-charts

Answer 3

I had a similar issue as well when I first tried out ChartKick. The error message that I got is Error Loading Chart: No charting libraries found - be sure to include one before your charts

Here's how I fixed it.

I simply added the following line of code below to the application.js file in the assets > javascript folder.

//= require Chart.bundle
//= require chartkick

Save and refresh, that should fix it.

That's all

I hope this helps.
