I will tell you all a very easy hack which u can use as a temporary fix for rating graph issue where it scrolls automatically.

Idea

So looks like Codeforces is using jquery.flot.navigate.min.js to have the mousewheel zoom effects, i noticed when i removed it the scrolling stopped. So, we can use an adblocker to prevent loading that script, and we can get a static graph as a result.

Steps

1. Install Adblock Extension for chrome
2. Go to the addon's options page
3. Add this URL to block filters jquery.flot.navigate.min.js
4. Done, Now for you all graphs would look static.
