I have a map of Germany, and the coords of a few cities.
plot displays the dots properly. I would like to use scatter instead, in order to be able to color the markets with respect to an other variable and then display a colorbar. The code runs in the console, but the dots are not visualized when I replace map.plot with map.scatter.

try adding "zorder" so that the points show up above the map:
map.fillcontinents(color='lightgray',zorder=0)
