r - Legend in loa plot -

I am trying to create a bubble plot in R in this command:

  GoogleMap (Zfit ~ lat * lon, xlim = c (12,13), ylim = c (45.1,45.9), main = "sonic year", panel = function (...) panel.zcasePiePlot (..., col = Rgb (102 / 256,178 / 256, 255/256, alpha = 0.6)))  

I am using the package loa . Here you can find the object:

Here's the plot: < / P>

Legend is different than what is plotted. How can I decide?
