凡例

Chart, Wikipedia

When the data appearing in a chart contains multiple variables, the chart may include a legend（＊凡例）(also known as a key). A legend contains a list of the variables appearing in the chart and an example of their appearance. This information allows the data from each variable to be identified in the chart.

[0360] FIG. 85 is a schematic representation of exemplary types of identifier legends accessible in a virtual world environment 2850 (e.g., game) to VW participants. For example, such VW participants may be members of a VW or RW group such as patron Koro 2855 , patron Moro 2856 and patron Soro 2857 . Other VW participants may have no current group membership such as patron Bega 2851 , patron Delu 2852 and patron Neki 2853 . It will be understood by those skilled in the art that different VW participants may pursue different roles in the virtual world environment 2850 , such as alter ego characters, avatars, anonymous facilitators, shop owners, object creators, performers, etc. and therefore may be exposed to or shielded from many different types of possible real-world opportunities.
