Matplotlib - fixing x axis scale and autoscale y axis

Question

I would like to plot only part of the array, fixing x part, but letting y part autoscale. I tried as shown below, but it does not work.

Any suggestions?

Answer 1

Autoscaling always uses the full range of the data, so the y-axis is scaled by full extent of the y-data, not just what's within the x-limits.

If you'd like to display a subset of the data, then it's probably easiest to plot only that subset:

import numpy as np
import matplotlib.pyplot as plt

x, y = np.arange(0,101,1) ,300 - 0.1*np.arange(0,101,1)
mask = (x >= 50) & (x <= 100)

fig, ax = plt.subplots()
ax.scatter(x[mask], y[mask])

plt.show()
