Lots of Notices/Warning when using Google Chart API

I gave this module a spin by installing Google Chart API (Chart API has had poor results in my experience). After installing the latest stable of Google Chart API (7.x-1.0-beta2) and following the instructions in README.txt to find the hidden settings page (thanks for that tip), I end up with these errors when viewing the Results -> Chart tab on my forms.

For every chart shown, I get these two PHP errors:

Notice: Undefined index: component in _webform_chart_backend_googleapilibs_config() (line 25 of /Users/nate/Sites/drupal7/sites/all/modules/webform_chart/includes/googleapilibs.inc).
Warning: array_key_exists() [function.array-key-exists]: The second argument should be either an array or an object in _webform_chart_backend_googleapilibs_config() (line 25 of /Users/nate/Sites/drupal7/sites/all/modules/webform_chart/includes/googleapilibs.inc).

The charts themselves still seem to work just fine however. I tried area, pies and bar charts, all seem to have the same error on the same line numbers.
