The formatter documentation makes it unclear how a PatternFormatter would be used through angular google chart. All of the other google chart formatters are initialized using an options object, but the PatternFormatter is unique in that it takes a string, like so:

var formatter = new google.visualization.PatternFormat('{0}');

and then a function is called to actually format the chart:
formatter.format(data, [0, 1]);

Is it possible to be provided an example of how this would be achieved in angular google charts?
