x: The X location of the center of the station plot, expressed in data coordinates.
y: The Y location of the center of the station plot, expressed in data coordinates.
Keywords
COLOR: The name of the color to draw the station plot in. May be a vector

Example
seed = -3L
lon = Randomu(seed, 20) * 360 - 180
lat = Randomu(seed, 20) * 180 - 90
speed = Randomu(seed, 20) * 100
direction = Randomu(seed, 20) * 180 + 90
