Using the graphs
- World: World or server number. 2 letter codes indicate the language for the server. EN for english, DE for german, etc (ISO 639-1 Language codes)
- P2P/F2P Lines: These are only available for the global graph for obvious reasons. F2P/P2P populations are estimated prior to roughly summer of 2008.
- Granularity: The level of detail in the graph. This adjusts the number of data points in the line. High = more. Low = less. Default is Medium. Graphs less than or equal to 12 weeks do not have a 'high' setting as medium displays all points.
- Start Date: The date at the left end of the graph.
- End Date: The date at the right end of the graph.
