Scatter matplotlib plot with different x starting points

Question

Is it possible to generate a figure like this:

1) Three different lines
2) Lines don't start at the 'same' x points
3) Later connect those scatter points with lines

t = [1, 2, 3, 4, 5, 6, 7]
a = [2, 3, .............]
b = [ , 1, 2, ..........]
c = [ ,  ,  ,  , 2, ....]

Thanks

Answer 1

Yes. You can use numpy.NaN for y-values without a corresponding t-value. The code would look something like this:

import matplotlib.pyplot as plt
import numpy as np
t = [1, 2, 3, 4, 5, 6]
a = [2, 3, np.NaN, np.NaN, np.NaN, np.NaN]
b = [np.NaN, 1, 2, np.NaN, np.NaN, np.NaN]
c = [np.NaN, np.NaN, np.NaN, np.NaN, 2, 8]

plt.plot(a,t, marker="o")
plt.plot(b,t, marker="o")
plt.plot(c,t, marker="o")
plt.show()

Output:
