Tally Graph Graph Plugin – Template Tag

I’m stumped.

I have created two custom fields (A and B) in a post called ‘Test’. A field value is 100, B field value is 200.

Then, I have inserted the following template tag into the single post.php:

Option A:

<?php echo tally_graph(‘key=A,B & chtt=TEST & method=track & interval_count=6 & tally_interval=year’); ?>

Option B:

<?php echo tally_graph(‘key=A,B & chtt=TEST & method=cumulative & interval_count=6 & tally_interval=year’); ?>

BUT with either option…rather than getting a graph that says November 2011 value is 100 and October 2011 value is 200 (with the other 4 months having no bar), I get a total of 300 for November 2011?
