Limit geo graph to specific region

A geo graph will show the entire world, by default. You may only show a specific region with the following code. Replace 'My graph title' with the title set in your graph shortcode. Replace 'IT' with the region of your choice. You may read more about the accepted regions here.

add_filter('frm_google_chart', 'frm_limit_graph_region', 10, 2);
function frm_limit_graph_region( $options, $args ) {
    if ( isset( $args['atts']['title'] ) && $args['atts']['title'] == 'My graph title' ) {
        $options['region'] = 'IT';
    }
    return $options;
}
