Quick Answer: To print a logarithmic x-axis or y-axis (base 10) without a Matplotlib axis object use plt.xscale(‘log’) or plt.yscale(‘log’). To set different bases or switch back to a linear scale, use {“linear”, “log”, “symlog”, “logit”} or set the basex and basey arguments (e.g., plt.yscale(‘log’, basey=2) for log base 2). Next, we’ll have a look … Read more
A Time Series is essentially a tabular data with the special feature of having a time index. The common forecast task is ‘knowing the past (and sometimes the present), predict the future’. This task, taken as a principle, reveals itself in several ways: in how to interpret your problem, in feature engineering, and in which … Read more

Problem Formulation Say, you’re me 👱♂️ five minutes ago, and you want to create a Matplotlib plot using the following (genius) code snippet: If you run this code, instead of the desired plot, you get the following TypeError: ‘AxesSubplot’ object is not subscriptable: 💬 Question: How to resolve the TypeError: ‘AxesSubplot’ object is not subscriptable … Read more
How to Plot a Circle in Python? You can easily plot a circle in Matplotlib’s Pyplot library by calling plt.gca() to “get the current axis”. Then call the axis.add_patch() function and pass a plt.Circle() object into it. For example, the one-liner plt.gca().add_patch(plt.Circle((0.5, 0.5), 0.2, color=’lightblue’)) adds a lightblue circle to the plot at position x=0.5, … Read more
💡 Grid lines are horizontal and vertical lines that span the chart to represent axis divisions. They assist chart readers in determining what value is represented by an unlabeled data point. Grid lines provide essential indications to the observer, especially for big or sophisticated charts. In this article, you will learn how to customize the … Read more
In this article, we’ll learn how to generate the Matplotlib color palette and then we will use it to select a specific color for our plot. Problem and Solution Overview Problem: When presenting data, the color that you assign to a plot is very important; a bad color choice can make your data difficult to … Read more
Preparation Before any data manipulation can occur, four (4) new libraries will require installation. The Pandas library enables access to/from a DataFrame. The NumPy library supports multi-dimensional arrays and matrices in addition to a collection of mathematical functions. The Matplotlib library displays a visual graph of a plotted dataset. The Scipy library allows users to … Read more
