Pull datasets from DB and manipulate into separate arrays
- by dresdin
My DB has four fields, date:date, morning:integer, afternoon:integer, evening:integer.
Google charts needs the data split into one array per dataset (example below). What's the best way to do this?
['Day', 'Morning', 'Afternoon', 'Evening'],
['06/27/13', 1000, 400 234],
['06/28/13', 1170, 460 275],
['06/29/13', 660, 1120 377],
['06/30/13', 1030, 540 934]
I've tried this without much luck:
var data = google.visualization.arrayToDataTable([
<% @todo.each do |t| %>
['Day', 'Morning', 'Afternoon', 'Evening'],
[<%= t.date.strftime("%m/%d/%y") %>, <%= t.morning %>, <%= t.afternoon %>, <%= t.evening %>]
<% end %>
]);
