Hey martynasma!
I absolutely love your plugin (it's the only one that actually looks good on WP) and am attempting to integrate it with my mySQL database.
The problem is, my JS and PHP knowledge is very limited and I'm learning it as we speak. I was wondering if you'd be able to help me out and guide me into what I need to put in the JS and HTML boxes (examples if possible..) if I want to create a chart to display an area chart with 'date_time' as the 'x' axis and 'profits' as the 'y' axis. I've tried to look at the PHP implementation page you have on your website but it fried by brain cells sadly..
If I can get this working, I'd be more than happy to donate, no idea how you can provide it to your users for free!
Many thanks,
Alex
