I am trying to use
<?php get_template_part( 'loop', 'charts' ) ?> to show a formatted loop in various of my templates. I have a loop-charts.php file with html and php code. The loop worked when it displayed in the template file but now does not display any posts when it's separated into the loop-charts.php file. I know it is getting the template file because if I add any arbitrary html, it displays that on the page. Just no posts.
