To generate random samples from a power-law distribution in Python, use the numpy library for numerical operations and matplotlib for visualization. Here’s a minimal code example to generate and visualize random samples from a power-law distribution: First, we import the necessary libraries: numpy for generating the power-law distributed samples and matplotlib.pyplot for plotting. The a … Read more
The distribution of wealth, especially when it comes to the ultra-wealthy, is a subject of immense fascination and study. It can reveal patterns and insights into economic structures, inequality, and financial dynamics at the highest levels. One of the most revealing ways to examine this distribution is through a log/log plot of the net worths … Read more
Here’s a minimal example of using colors in Matplotlib. This example creates a simple line plot with a specified color: In this minimal code example, plt.plot(x, y, color=’red’) creates a line plot of x versus y, with the line color set to red. You can replace ‘red’ with other color names like ‘blue’, ‘green’, etc., … Read more

I tried a few helpful applications of Google Bards Image Recognition capabilities for coders. I don’t know about you but I often see beautiful plots (e.g., in research papers or data science reports) and wonder how I could recreate them. Well, Google Bard to the rescue! ✅ Reverse Engineer Exponential Plot in 2D First, let’s … Read more
To create a 3D surface plot of a bivariate normal distribution define two normally distributed random variables x and y, each with its own mean (mu_x, mu_y) and variance (variance_x, variance_y). The random variables are independent,the covariance between x and y is 0. Use the grid of (x, y) pairs to calculate the probability density … Read more
Problem Formulation The output when running this code is as follows Warning (from warnings module): File “C:\Users\xcent\Desktop\code.py”, line 10 ax = fig.gca(projection=’3d’) MatplotlibDeprecationWarning: Calling gca() with keyword arguments was deprecated in Matplotlib 3.4. Starting two minor releases later, gca() will take no keyword arguments. The gca() function should only be used to get the current … Read more
To generate a 3D waterfall plot with colored heights create a 2D sine wave using the NumPy meshgrid() function, then apply a colormap to the heights using Matplotlib’s Normalize function. The plot_surface() function generates the 3D plot, while the color gradient is added using a ScalarMappable object. Here’s a code example for copy and paste: … Read more
Are you tired of feeling boxed in by your Python plots and ready to break free from the constraints of traditional legend placement? In this guide, I’ll show you how to put legends outside your plot for (click to 🦘 jump): Let’s start with the first! 👇👩💻 Matplotlib Put Legend Outside Plot Let’s start with … Read more
As a parent, planning for your children’s future is one of the most important things you can do. To ensure they have the best possible start in life, I’ve been looking into ways to invest money to provide them with a lump sum of $70k when they reach 21. But I don’t want to spend … Read more
In this article, you’ll learn how to make this beautiful and interesting animation using only Python, NumPy, and Matplotlib — nothing else: 👇 But how does the Game of Life work – and what’s behind the classical visualization anyways? The Game of Life Conway’s Game of Life is a cellular automaton devised by the British … Read more
💬 Question: How can I return a Matplotlib axis, plot, or figure object in Python so I can set some defaults and plot a figure quickly based on those defaults? Basic Solution To return a Matplotlib object from a function, follow these steps: 👇 Create a function my_plot(x, y, …) with arguments to customize your … Read more
