How to hide lines in matplotlib?

Question

I do not want to connect points with lines. I know that for that I can use scatter. But, scatter does not work after plot.

So, basically I have to lists of points. The points from the first list I do want to connect with lines while the points from the second list should not be connect with lines.

How can one achieve it in matplotlib?

This is what I have tried:

plt.figure()
plt.plot(xys[:,0], xys[:,1], marker='o', color='g')

# WHAT SHOULD I DO HERE?
#plt.plot(xys_bad[:,0], xys_bad[:,1], color='r', linewidth=0.0, markersize = 10.0)
plt.scatter(xys_bad[:,0], xys_bad[:,1], color='r')

plt.show()

As describe in matplotlib documentation you should use the 'None' linestyle:

plt.plot(xys_bad[:,0], xys_bad[:,1], color='r', linestyle='None', markersize = 10.0)

so weird that `linestyle=None` does not work. It must be a string. – matiasg Oct 09 '19 at 13:35

For me, this removes the line altogether. How do I keep the points? – Rylan Schaeffer Apr 20 '20 at 20:02

@RylanSchaeffer: Maybe your forgot to add the `marker` property. – s.ouchene Jul 07 '20 at 17:02
@RylanSchaeffer I used `marker = "."` and that worked. (following s.ouchenes advice) – ions me Nov 28 '22 at 03:37
