Google Charts trendline y-intercept

How can I change the background, text color, etc. of the individual cells? Thank you.

Per @Bondye's comment, the answer is found in the developers guide.

Define style rules that match your criteria:

<style>
.orange-background {
   background-color: orange;
  }

 .orchid-background {
  background-color: orchid;
 }

.beige-background {
 background-color: beige;
  }
</style>

Apply them to the table when drawn.

var cssClassNames = {
'headerRow': 'italic-darkblue-font large-font bold-font',
'tableRow': '',
'oddTableRow': 'beige-background',
'selectedTableRow': 'orange-background large-font',
'hoverTableRow': '',
'headerCell': 'gold-border',
'tableCell': '',
'rowNumberCell': 'underline-blue-font'};

var options = {'showRowNumber': true, 'allowHtml': true, 'cssClassNames': cssClassNames};

var data = new google.visualization.DataTable();

//... add data here ...

var table = new google.visualization.Table(container);
table.draw(data, options);

You can also test what the jobs will do by running them or turning off queuing.

Tweak config whenever you want (i.e. in a before :each block).

Delayed::Worker.delay_jobs = false

or perform your saved jobs

Delayed::Worker.new.work_off.should == [1, 0]

I have been using this method happily for a while. For one thing, using the new any_instance support in RSpec, you can test your delayed methods effects directly. However, I've found tests that use work_off to be slow.

What I usually do now is:

mock_delay = double('mock_delay').as_null_object
MyClass.any_instance.stub(:delay).and_return(mock_delay)
mock_delay.should_receive(:my_delayed_method)

Then I have a separate spec for my_delayed_method. This is much faster, and probably better unit testing practice -- particularly for controllers. Though if you're doing request specs or other integration-level specs, then you probably still want to use work_off.
