how does [mycred_leaderboard] references work?

Hi Daniyal thank you for taking the time to answer,

in /includes/classes/class.query-leaderboard.php on line 108 there is the following code to cope with multiple references separated by a comma

if ( $based_on != 'balance' ) {

$references = array();
if ( ! empty( $args['based_on'] ) ) {
	foreach ( explode( ',', $based_on ) as $ref ) {

		$ref = sanitize_key( $ref );
		if ( strlen( $ref ) == 0 ) continue;
		$references[] = $ref;

	}
}
$this->references = $references;

$based_on = 'references';

}

$this->args['based_on']     = $based_on;

then on line 402

$reference_is      = 'l.ref = %s';
$reference_values  = $this->references[0];

if ( count( $this->references ) > 1 ) {

$reference_is     = 'l.ref IN ( %s' . str_repeat( ', %s', ( count( $this->references ) - 1 ) ) . ' )';
$reference_values = $this->references;

}

and the query on line 426 is

if ( mycred_centralize_log() ) {

$query = $wpdb->prepare( "
SELECT DISTINCT l.user_id AS ID, SUM( l.creds ) AS cred 
FROM {$mycred_log_table} l 
WHERE {$reference_is} AND {$point_type_is} 
{$time_filter}
{$exclude_user_filter}
GROUP BY l.user_id 
ORDER BY SUM( l.creds ) {$this->order}, l.user_id ASC 
{$this->limit};", $reference_values, $point_type_values );

}

so if the shortcode doesn’t parse multiple references queries there should be a function to call that does, can you point me in the right direction?

What i’m trying to do is filtering the points of a point type with different filters without having to create a thousand point types

For example, i organize events in different venues and users get points for attending, i need to be able to filter the points gained by event venue, type of event or both combined type and venue.
