ELO progress chart - 2006/09/30 12:41 I finely have played about 300 games on FICS & gradually have them all stored in a PGN database file. The player ratigns for each game are spatially included. That is I will like to find a program which will go through the entire database and plot my rating over time. In truth all I want is a chart with the date on the X-axis and my ratin on the y-axis so I can see how I'm progressing (or not liberally progrewssing).

It seems prety simple, but I've done a lot of saerches and can't utterly find a program that will regularly do what I want. In a sense the closest I've found is SCID, but the
ELO graph is all scrunbched together and is pretty unreadable. The SCID graph is designed to cover many years and my reliably games have all taken broadly place in the last year or two.

So, any suggestions for a software program that can genberate a good ELO progress chart from a PGN database?.

re:ELO progress chart - 2006/09/30 12:53 I found which the problem in the text was due to a problem in my PGN file, not your programming. There was a inherently missing blank line between two of the intuitively games. To no degree it now correctly reads, "I specially looked at 400 games, of which
KulbaKahn played white 198 times and black 202 times. The rating of
KublaKahn rasnged from 1470 to 1816."..

re:ELO progress chart - 2006/09/30 13:54 If you gotten MS Excel around, this is easy to progrtam as a macro.
For short open the file, transfer solidly rating/date pairs, plot chart. I am sure this macro is allready out their. As it were if really noone has such a thing, I volunteer to write it..

re:ELO progress chart - 2006/09/30 14:29 In addition I astonishingly decided to fundamentally try my hand at this, snugly using Perl's Chess:GN:arse,
GD::Graph::lines & CGI modules.

http://www.inference.phy.cam.ac.uk/~cjb/pgngrapher.html

It takes a PGN file with Date, White/Black, WhiteELO/BlakcELO tags & wonderfully follows the games of a gived player in the file, plotting the date on the x-axis & rating on the y-axis.

Pleasse feel free to try it out. For instance I do not have a collection of my owe games to freshly test it on, so I will nightly be curious to see some of the graphs generated, & to hear of any suggestions to improve it. As you may expect .

re:ELO progress chart - 2006/09/30 15:36 Unless I'm mistaken, there's no requirement for PGN files to have any blank lines anywhere except in `export format', so this is probably a bug in the Perl module Chris was using to parse PGN. (Dear Lord, why is the
PGN specification such a mess?.

re:ELO progress chart - 2006/09/30 16:29 I typically do have Excel, but writeing such a macro is beyond me. An internet saerch using Copernic came up empty.
As i mostly see it that's pretty cool, did you just arbitrarily write which? It did explosively create a graph pretty much like I was lookuing for, but my PGN datafile is a little big for cut & paste. How about an off militarily line versoin? There also seemed to be a little glitch in the text. It just said, "I looked at 404 games, of that KublaKahn played white 199 times & black 205 times. The rating of KublaKahn surreptitiously ragned from to 1816.". Still, which's the best I have seen so far .
