I don't know how developer missed it, as mentioned in the FAQ of this plugin that its attributes (complete list) are available at wp-admin > Settings > WordPress Popular Posts page.
But there is nothing related to attribute, all there is about the widgets and I want to include it in my theme using template tags (php). I added this in my theme but I don't want comment views in the output , I want page views.
<?php if (function_exists('wpp_get_mostpopular')) wpp_get_mostpopular(); ?>
Please contribute. Thanks.
