Cool plugin, looks really nice.
Installed the plugin last night and saw the blank graphs, but I figured it must need to collect some stats overnight. Today these graphs in the subject line are all still blank.
My site is http://www.fabrics.net and we have hundreds of visitors per day, so not sure what I'm doing wrong.
I've read and re-read teh readme.txt and I've deactivated/reactivated the plugin and still no change. What else should I check?
