A square wave is a type of non-sinusoidal waveform that is widely used in electric and digital circuits to show signals. Basically, these circuits use a square wave to represent input and output or on and off. Python provides several ways to plot square waves including Matplotlib, NumPy and Scipy libraries. These libraries offer various built-in methods for data visualization, making it easy to create and customize square wave plots. Python Program for plotting a Square Wave Before discussing the example programs, it is necessary to familiarize ourselves with the basics of Matplotlib, NumPy and Scipy libraries. ... Read More

A line graph is a common way to display the relationship between two dependent datasets. Its general purpose is to show change over time. To plot a line graph from the numpy array, we can use matplotlib which is the oldest and most widely used Python library for plotting. Also, it can be easily integrated with numpy which makes it easy to create line graphs to represent trends and patterns in the given datasets. Python Program to Plot line graph from NumPy array Here are the example programs that demonstrate how to plot line graphs from numpy ... Read More

Numpy is a powerful Python library that serves to handle large, multi-dimensional arrays. However, when printing large numpy arrays, the interpreter often truncates the output to save space and shows only a few elements of that array. In this article, we will show how to print a full Numpy array without truncation. To understand the problem statement properly, consider the below example: Input aray = np.arange(1100) Output [ 0 1 2 ... 1097 1098 1099] In the above example, we have created an array with 1100 elements. When ... Read More

Pandas is a powerful Python library mainly used for data analysis. Since it contains large and complicated numeric datasets that are difficult to understand, we need to plot these datasets which makes it easy to visualize relationships within the given dataset. Python provides several libraries such as Matplotlib, Plotly and Seaborn to create informative plots from the given data with ease. In this article, we will show how to plot the size of each group in a Groupby object in Pandas. Python Program to Plot the Size of each Group in a Groupby Object To plot the ... Read More

Finding the percentile rank is a common operation that is used for comparison between data of a single dataset. The end result of this operation shows a certain percentage is greater than or equal to the specified percentile. For instance, suppose a student obtains a score greater than or equal to 80% of all other scores. Then, the percentile rank of that student is 80th. To find the percentile rank of a column in a Pandas DataFrame, we can use the built-in methods named 'rank()' and 'percentile()' provided by Python. Python Program to find Percentile Rank of ...

Hierarchical data is often used to represent multiple levels of nested groups or categories. For example, a company may have a hierarchy of employees, departments, and locations. A product may have a hierarchy of categories and subcategories. One of the challenges of working with hierarchical data is how to represent it in a tabular format which can make it easy to manipulate and analyze. In this article, we are going to present hierarchical data using Pandas' built-in methods like 'set_index()' and 'groupby()'. Python Program to Represent Hierarchical Data using Pandas First, let's briefly discuss Pandas and its ... Read More
