I used to write a crawler to fetch each bet's data, and want to do some analysis. But Doog use CloudFlare to protect the site again this...
I think unless doog generate this plot for you, there is no other way you can do instead. Maybe doog has the design of the API of the site in his mind?

This is a bad idea.... The amount of data you get (in bytes) for requesting bet info is much more than placing a bet or doing just about anything else on the site, so crawling for all bets will increase traffic to the server immensely. Besides, it's extremely hard to pull data for 50 bets every second.
There is a site that has charts,
https://bitcoinproject.net/justdice.php . This should show almost everything you need except the actual bet data.
There is an api link where you can get data like amount of rolls, invested amount, profit, etc, but i cannot remember what the link is. I'm sure Doog will give it to you if you ask.
