<%= pie_chart [{label: 'Hello World', data: 50}, {label: 'Foo', data: 25}, {label: 'Bar', data: 25}] %>If you prefer placing your scripts in header instead of the body, then use something like this:
<!-- views/my_controller/index.html.erb -->
<%= chart(@chart_data, split: true, grid: {hoverable: true}) %>
<%= yield_chart_script_at :flot %>and append a yield in your layout's head:
<!-- views/layouts/application.html.erb
<head>
<%= yield :flot %>
</head>
