PGNGrapher

PGNGrapher is a simple tool to graph the chess rating of a single player over time, using the Date and WhiteELO/BlackELO tags of a PGN file. A common use is with game logs from a server such as FICS or ICC, since these logs feature all the data needed to make a graph.

The Perl source code is available, along with some example output.

Paste the PGN file here:

Enter the player to graph, exactly as written in all of the games in the PGN file:
