I want to rotate the xtick labels in this multi-axis plot (the code I use for a single axis plot doesn't work).
What the xtick labels should look like (ignore the different dates)
The code
import numpy as np
import matplotlib.pyplot as plt
from mpl_toolkits.axes_grid1 import host_subplot
from mpl_toolkits import axisartist
# Create the data
data = {
'Date': pd.date_range('2021-01-1', '2021-01-30'),
'Close': np.linspace(100, 200, num=30) + np.random.normal(scale=10, size=30),
'Volume': np.random.randint(500, 2000, size=30)
}
df = pd.DataFrame(data)
df = df.set_index(df.Date)
# Create the axis
plt.figure(figsize=(10,5))
host = host_subplot(111, axes_class=axisartist.Axes)
ax1 = host.twinx()
ax1.axis["right"].toggle(all=True)
# Plot the closing prices
line, = host.plot(df.index, df.Close, label="Close")
host.set_ylabel("Close")
host.yaxis.label.set_color(line.get_color())
# Plot the volumes
bar = ax1.bar(df.index, df.Volume, alpha=0.2, color='red', label="Volume")
ax1.set_ylabel('Volume')
ax1.yaxis.label.set_color('red')
host.legend()
plt.show()
The code is based on this matplotlib example:
https://matplotlib.org/stable/gallery/axisartist/demo_parasite_axes2.html#sphx-glr-gallery-axisartist-demo-parasite-axes2-py
Normal solutions for single-axis plots don't work, eg. Rotate axis text in python matplotlib
