Y axis title keeps clearing when viewing settings (fix included)

It's a simple issue.

A line is missing in 'visualization/includes/views/visualization_plugin_style.inc' on line 121

$form['yAxis']['title'] = array(
'#type' => 'textfield',
'#title' => t('Y-axis title'),
+ '#default_value' => $this->options['yAxis']['title'],
);

That's it!
