When there are many data points in a pie chart and you want to highlight the most important data points or bring lesser data points together for better visualisation, pie of pie and bar of pie charts might be helpful. These chart types offer a succinct way to clearly display both the broad distribution and the particular details. You will be guided step−by−step through the process of making Excel Pie of Pie and Bar of Pie charts in this tutorial. Regardless of your level of Excel proficiency, this video will assist you in mastering these chart formats and improving your ... Read More
Introduction The exec command is a built-in command in the Unix and Linux shell that allows a user to execute a command or a script in place of the current shell. This means that the exec command is used to replace the current shell process with a new process, which can be a command or a script. The exec command is useful in shell scripts when you want to execute a command or a script and then exit the current shell. Syntax of exec command −Example $ exec: exec [-cl] [-a name] [command [argument ...]] [redirection ...] Why should ... Read More
Contextual selectors allow the developer to select different types of styles for different parts of the document. In CSS, the developer can either specify styles directly or by making certain classes. The contextual selector will only apply the style to the elements which are specified. A parent-child relationship between elements in the document can be known as context. The contextual selectors will have 2 or more than 2 selectors which are separated. In this article, we are going to have a look at what is a contextual selector in CSS and how can we use it. What is contextual selector ... Read More
The task we are going to perform in this articles is to “Remove property for all objects in array in JavaScript”. A collection of key-value pairs constitutes an object in JavaScript. A key-value pair among them is referred to as an object property. Any data type, including Number, String, Array, Object, etc., can be used for both the keys and values of properties There are two methods: one is mutable and uses the delete operator; the other is immutable and uses object restructuring. Let’s discuss this method. The delete operator The delete operator eliminates both the property's value and the ... Read More
Visualizing data is a crucial part of data analysis, as it can help to uncover insights and reveal patterns in complex datasets. Circular visualizations are a unique approach to visualizing data, which can be particularly useful in identifying relationships and patterns that are not immediately apparent using traditional graphing techniques. This article will provide a comprehensive guide to creating circular visualizations using the Hishiryo Python library. We will explore the advantages of circular visualizations, delve into the basics of the Hishiryo Python library, and demonstrate how to create circular visualizations using different types of datasets. Upon completion of this article, ... Read More
To obtain the canvas's image data URL, we can use the canvas object's toDataURL() method, which converts the canvas drawing into a 64 bit encoded PNG URL. You can pass image/jpeg as the first argument to the toDataURL() method if you want the image data URL to be in jpeg format. You can control the image quality for a jpeg image by passing a number between 0 and 1 as the second argument to the toDataURL() method. Any images drawn onto the canvas must be hosted on a web server with the same domain as the code executing it, according ... Read More
JavaScript relationships with the HTML/CSS file, particularly with the Document Object Model (DOM), are made easier through an open-source library called "jQuery". Its traversal and manipulation of HTML files, the control of browser events, the production of DOM visuals, the facilitation of Ajax connections, and cross-platform JavaScript programming are all made easier by this package. To verify whether a particular string constitutes a substring of another string, JavaScript provides a variety of string functions. Consequently, jQuery is dispensable to accomplish this task. Nonetheless, we shall expound on the various approaches to verify if a string commences or terminates ... Read More
Web scraping has evolved as an effective method for obtaining information from websites. It allows individuals and organizations to collect information for a variety of objectives, including market research, sentiment analysis, and data−driven decision−making. However, online scraping frequently produces unstructured and jumbled data that must be cleaned and preprocessed before it can be used efficiently. The clean−text module in Python provides a complete and efficient solution for cleaning web scraping data, allowing users to preprocess and extract important insights from their scraped data. Clean−text is a robust Python package for text cleaning and preprocessing. It includes a variety of functions ... Read More
In today's digital age, efficiently categorizing text documents has become crucial. One approach to this is using sparse features in Python's Scikit−Learn library. Sparse features involve representing each document as a high−dimensional vector, with each dimension corresponding to a unique word in the corpus. In this article, we'll explore the theory and implementation of text classification using sparse features in Scikit−Learn. You'll gain practical skills in data preprocessing, feature extraction, model selection, and evaluation. Whether you're a researcher, data scientist, or developer, this article will provide valuable insights into text classification using Python. Getting Started Sparse feature representation is a ...

Python is a highly flexible programming language that allows for various programming patterns. One of these patterns is the class factory pattern, which is a powerful way to create classes dynamically at runtime. In this article, we'll explore the class factory pattern in Python and its benefits, and provide some examples of how it can be used to write more modular and flexible code. How Class Factories Work A class factory is a special type of function that generates a brand new class when it is called. This function typically takes input parameters that are used to define the properties ... Read More
