Question

Use case : plotting in Matplotlib, say.

import numpy as np
orig = np.arange(0, 30 + 0.5, 0.5)
extra = orig - 0.01  # I'm interested in a few extra values

x = np.???(orig, extra)

What I want is to somehow merge (I guess a sort is also needed for the current use case) these two arrays (not always of the same size) so that I can use it for a subsequent plot?

Answer 1

If I understood you correctly, you’re looking for

x = np.sort(np.hstack((orig, extra)))

Here, hstack() merges the two arrays, and sort() sorts the result.
