Answer 1

Is it an option to just make a thick white border around your markers? Its not a custom linestyle but a simple way to get a similar effect:

y = np.random.randint(1,9,15)

plt.plot(y,'o-', color='black', ms=10, mew=5, mec='white')
plt.ylim(0,10)

Here the key are the arguments

• mec='white', white marker edge color
• ms=10, markersize 10 points (this is rather large),
• mew=5, marker edge width 5 points, such that effectively the points are 10-5=5 points large.
