Support for Google Charts DataTable Roles about chartkick

[ankane]

No, which roles are you interested in?

[shinnc]

I'm interested in the customizable tooltip, here's my attempt: shinnc@0a03399

It works for me now but I wish there's an official implementation :)

[ankane]

What's the code to call it look like?

[shinnc]

data = [ ["foo", 1, "tooltip for foo"], ["bar", 2, "tooltip for bar"] ]
column_chart data, library: { tooltip: true }

Ideally it should be

data = Task.group_by_day_of_week(:created_at).count
column_chart(data, role: {  tooltip: ["tooltip for A", "tooltip for B"], other_roles_here... })

[ankane]

Closing in favor of #46

Will this be merged into the main branch?

[ankane]

This won't, but will gladly accept a pull request for a slightly different format:

column_chart [{label: "Hello", value: 1, tooltip: "World"}, ...]
