[Matplotlib-users] plotting a colored symbol with plot command

[Michael R. <raw...@ya...>]

Relatively new user here. I need to place a series of white colored dots on a map. I've been able to place black dots using:

plt.plot(x,y,color='k',marker='.',markersize=3.0)

The color option in this command does not plot the chosen color, only black. The command:

plt.plot(x,y,'wo')

places white dots with black around the edges.  I see that the 'w' is for white and 'o' is for the symbol. I'd like to use the former command since that gives me control over marker size and a dot without a black edge.

Lastly, it's not clear to me if I should be using plt.plot or just plot. Both work, and I don't know the difference.
