Rank Graph

[mogosoup]

Is it possible to extend the rank graph to seem more than one year of data?

[Toge]

It is not possible.

I would like to request that this feature be added. It would be really nice to be able to see how someone has improved over say, 5 years.

You could always take KGS View (http://www.geocities.jp/msanpopo/kgs.html) to see something like that. It's almost an offline version of KGS Analytics (kgs.gosquares.net) with a lot more features.

And don't be confused when the site is all in Japanese. The software itself is in English.

I don't save rank information from more than 400 days ago. It would be possible to recaculate ranks for a given point in time, because all game win/loss information is saved permanently, but that would take a lot of compute power.

Back when I used to play on KGS a lot I took screenshots of my rank graph with the idea to stitch them together for a fuller history (but never did).

Same here ...

Is there a way to stick em together into one picture? Photoshop panorama tool?

I agree that an account full-life rank graph would be awesome , as all win/loss information is saved, maybe it could be calculated and plot on the client side, as a script (so almost no aditional computation effor would be required in the server, neither lot of programming work).

I also used to snapshot my rank graph, I think that we all do at some point (every one likes to analyze his own improvement).

What would be fairly easy to do is make a new graph for yourself using only declared rank at the time of a game. It would be a little crazy to use your client to download every game ever played on KGS and recalculate all the rankings since the beginning of time.

Edit: Looks like JTS beat me to the punch, but just to expand on what he was saying:

Your rank on KGS at any given time is based off of everyone else's rank at that time (which is in turn based off of all their wins and losses as well). Calculating your rank graph based off of a game history would require calculating everyone else's rank graph as well, and would require having the full database of all won and lost game results on KGS (not only your own). It might not be too hard to program (since the rank calculation engine is already there) but it would take quite a bit of computing time.

Right, I was also refering to recalculate and plot it only in using the declared rank on your game records (that acts like snapshots of the precalculed rank... I don't think that they save it more than one per day), that's why I said it was trivial client side (is just reuse the ploting program codelines adapting it to use pairs <game rank, game date> and using some interpolation to avoid jumps). It would only differ from the original ranking if during a long hiatus.


Of course, recalculate all the ranking data from the begining of time would be no-sense, even more to do it client-side (neither the server side, at least as a short-time proyect and kwoning that takes extra space), but I don't think that anybody is hoping that kind of precision, is quite useless as the difference can only be noticed during the hiatus.

It will also lose the spikes and precision between one rank and another, but we are talking of graphs that have more than one year long (we have the other plot), so that wouldn't be almost apreciated anyway due to the lenght of the graph and density of the data.
