I can't figure out how to rotate the text on the X Axis. Its a time stamp, so as the number of samples increase, they get closer and closer until they overlap. I'd like to rotate the text 90 degrees so as the samples get closer together, they aren't overlapping.
Below is what I have, it works fine with the exception that I can't figure out how to rotate the X axis text.
import sys import matplotlib matplotlib.use('Agg') import matplotlib.pyplot as plt import datetime font = {'family' : 'normal', 'weight' : 'bold', 'size' : 8} matplotlib.rc('font', **font) values = open('stats.csv', 'r').readlines() time = [datetime.datetime.fromtimestamp(float(i.split(',')[0].strip())) for i in values[1:]] delay = [float(i.split(',')[1].strip()) for i in values[1:]] plt.plot(time, delay) plt.grid(b='on') plt.savefig('test.png')

Rotate X-Axis Tick Labels in Matplotlib There are two ways to go about it - change it on the Figure-level using plt. xticks() or change it on an Axes-level by using tick. set_rotation() individually, or even by using ax. set_xticklabels() and ax.
In Matplotlib we can reverse axes of a graph using multiple methods. Most common method is by using invert_xaxis() and invert_yaxis() for the axes objects. Other than that we can also use xlim() and ylim(), and axis() methods for the pyplot object.
This works for me:
plt.xticks(rotation=90) If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
