NAME
Jifty::Plugin::Chart::Renderer::GoogleViz - chart renderer using Google Charts JS
init
We need to load Google's JS.
render
load_params
Load the "packages" required for the visualization; define a "packages_to_load" method which returns a list of them.
render_data
Renders the columns and the data.
add_columns
Adds the columns to the visualization. Each column is a key-value pair; the key is the column's "id" and the value is either a string (the "type") or a hashref. The hashref may specify "type" and "label". If no "label" is given, the "id" is used.
It will return a hashref of canonicalized columns.
add_data
Adds the data to the chart. Each data point should be a hash reference of column id to value.
