You can use FONT= to specify a symbol font, such as Marker, that contains a symbol that you want to use in your plot. In this case, the string specified by VALUE= is the character code for the symbol. For example, this definition specifies a heart:

symbol font=marker value=N;

You can also use FONT= to specify a text font, such as Swiss. In this case, the string specified by VALUE= appears in the plot:

symbol font=swiss value=star;

这标题我就没看懂

O(∩_∩)O~   看了帖子后还是不明白标题意思

在symbol statement中，value的值及表示的图形。

谢谢
