Error messages might be helpful.
The error message is
undefined method `to_js' for nil:NilClass
I wrote this into controller
def gauge
data_table = GoogleVisualr::DataTable.new
data_table.new_column('string' , 'Label')
data_table.new_column('number' , 'Value')
data_table.add_rows(3)
data_table.set_cell(0, 0, 'Memory' )
data_table.set_cell(0, 1, 80)
data_table.set_cell(1, 0, 'CPU' )
data_table.set_cell(1, 1, 55)
data_table.set_cell(2, 0, 'Network')
data_table.set_cell(2, 1, 68)
opts = { :width => 400, :height => 120, :redFrom => 90, :redTo => 100, :yellowFrom => 75, :yellowTo => 90, :minorTicks => 5 }
@Chart = GoogleVisualr::Interactive::Gauge.new(data_table, opts)
end
And i wrote this into view
<%= render_chart @Chart, 'chart' %>
The gem file is correctly bundled
The code seems alright to me. Does your view have a div with 'chart' as the id?

Yes, but during the copy/past it is not visible...i don't know why
May be' a conflict with anithe gem?
Anyway, thank for your help
Have you solved it?
