Rotating Axis Tick Labels for Non-Overlapping Time Stamps
When dealing with time-stamped data, the increasing number of samples often leads to cluttered and overlapping tick labels on the X axis. To prevent this and improve readability, rotating these labels can be beneficial.
Solution:
To rotate the X axis tick labels, you can simply append plt.xticks(rotation=90) to your existing code. This will rotate the labels by 90 degrees, making them vertical and less likely to overlap.
Code Snippet:
Below is your code with the addition of the plt.xticks(rotation=90) line to rotate the X axis tick labels:
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.xticks(rotation=90) # Rotate the X axis tick labels by 90 degrees plt.savefig('test.png')
By incorporating this line into your code, the X axis tick labels will be displayed vertically and more legible, even as the time stamps become more frequent and closer together.

You can manage different Python versions by using pyenv, venv and Anaconda. 1) Use pyenv to manage multiple Python versions: install pyenv, set global and local versions. 2) Use venv to create a virtual environment to isolate project dependencies. 3) Use Anaconda to manage Python versions in your data science project. 4) Keep the system Python for system-level tasks. Through these tools and strategies, you can effectively manage different versions of Python to ensure the smooth running of the project.

The impact of homogeneity of arrays on performance is dual: 1) Homogeneity allows the compiler to optimize memory access and improve performance; 2) but limits type diversity, which may lead to inefficiency. In short, choosing the right data structure is crucial.
