Chrome/Firefox Extension to analyse Codeforces profiles
By apoorva222g, history, 2 years ago, In English

Hello coders!!

Recently I have developed a chrome extension which analyses codeforces profiles and presents the chart/data on the profile webpage itself. Just open any profile on Codeforces after installing this extension.

Install Now for Google Chrome

Install Now for Mozilla Firefox

Also, you can find the source code on Github.

The chart includes —

  1. Problem rating chart — Bar chart for the number of problems solved for each problem rating
  2. Tags chart — Doughnut chart for the number of problems solved for each tag across all problems
  3. Unsolved problems — Gives the count and also lists all unsolved problems.

Extension in action:

The UI blends easily with the original website.

Thanks for a nice extension! However, when I opened the profile of vjudge3, data loading was not completed even after a few minutes XD

This is really a good idea, but why does your extension want to see my browser history?

    No the code does not read any browsing history. It might be showing so because of tab permissions required to open your profile from the extension popup. Anyways I'll look into this for an update.

      But reading the browser history has nothing to do with opening a tab. I apologize for such paranoia, but I will not risk putting something as long as it wants to read my browser history even if according to you it does not do this

    ThankYou! for highlighting this issue. I have updated the extension, the new version now does not require any permission to read browsing history. Old versions currently installed will automatically be updated by the Chrome browser.

Nice work! I have a couple of suggestions though

If we look at Agnimandur (at least at the time of my comment), there are a couple of issues

1) If you don't pay close attention you can miss that he has zero solves for 3000-3200 rated problems and there is a jump from 2900 to 3300 in the histogram. Personally I'd like to see empty columns there. And you don't have to make all columns up to 3500 if someone only solves problems below 2000, just make them if they are in the middle

2) It's impossible to hover over 3300 or 3400 column. I don't know how it works but maybe limit minimum height of bounding box?

    Ha ha, my only 3000+ rated solves are for problems in my own round :D.

Does this give you ability to look at other people's code during contest? Maybe I should disable it while giving an ongoing contest.

Hey apoorva222g, this a GREAT extension. I had been searching for something like this. And now I don't have to visit cfviz site for the stats! Thanks a bunch. Hoping to see more cool upgrades.

I cant thank you enough for this extension ! Thanks a lot !

One feature suggestion / request which I think will be more helpful : Range sliders in the problem solved rating bar chart. What I mean by sliders is,I get some kinds of sliding buttons that can help me fix a range for which I want to see the graph, for eg : lets say I only want to see the problem ratings solved for range [1600,2000]. I think this helps a lot when you try to analyse your stats to deeper levels. Looking forward to hear your views on it apoorva222g

I have been using the extension for a long time now but I never noticed who made it and today while I was reading this blog I thought of adding this extension to my firefox but when I clicked on the link, I found out that it was CF-anylatics.

Thanks for this amazing extension :)

    Yes, me too. This extension depends on the Codeforces API, which is currently not working. I hope they fix it soon.

Thank you for this extension; I have been using it for a while and it's so useful.

One thing that bothered me was that I was guilty of solving many 800-rated problems which made the rating chart less beautiful, so I edited the extension and added a menu that allows filtering the problems by both rating and date range, which I think it would be helpful to track progress within a specific time frame.

Then made a pull request in case it could be useful to someone.
