Dear Dennis, it would be better if not plotting the lon and lat. Keeping it
blank is better for the aesthetics of my map.
I am not sure how I can give a reproducible example herebut I want to
ggmap(mp, darken = 0) + geom_point(aes(Longitude, Latitude,
colour=Divergence), data = PlotPoints, size =10)+
scale_colour_gradient2(low=muted("red"),mid="green", high=muted("blue"),trans
="log")+geom_point(aes(Longitude,Latitude),size=15,data=stationaryPoint,colour="Red",shape="X",size=15)
log10(seq(1,20,length.out=100))
to make the color scale with fixed colors (0.3 for green for example) and
increase it in size so the numbers in the bar are still visible when the figure
is getting smaller in size

Hi Alex:
The documentation for ggmap tells you that its x-y coordinates are
lat-long. What did you want to plot instead?
There are several theme options for legends, as well as a few more in
the guide_legend() function. As far as the color scale, you should be
able to set it with hex codes in each map.
Since there is no reproducible example with which to work, I can't
really help/comment much further. If you come up with one, please post
it back to the group so that others can see it. Some of them have more
experience with mapping in ggplot2 than I do.
