Recently, while working on a Python data visualization project for a U.S.-based retail company, I encountered a frustrating issue. I was trying to create a stacked bar chart using Matplotlib, but the bars didn’t align properly, and sometimes, the totals didn’t add up as expected. If you’ve ever faced similar errors while working with Matplotlib … Read more >>
Working on a data visualization project where I needed to show both positive and negative values in a single stacked bar chart using Python. At first, I thought it would be easy, but I quickly realized that handling negative values in a stacked chart requires a little extra care. In this tutorial, I’ll show you … Read more >>
Recently, I was working on a data visualization project where I needed to create multiple stacked bar charts dynamically using Python. The challenge was that I had dozens of categories, and writing each plt.bar() line manually wasn’t practical. That’s when I realized how powerful a simple for loop in Python could be for automating stacked … Read more >>
Recently, I was working on a Python data visualization project where I needed to display the same dataset on two Y axes in a single Matplotlib chart. At first, I thought this would be a simple task, but I quickly realized that setting up dual Y axes in Matplotlib can be a bit tricky if … Read more >>
I was working on a data visualization project where I needed to show the performance of different product categories across several U.S. regions. I wanted to use a stacked bar chart because it’s an excellent way to display the contribution of each category to the total value. While Matplotlib makes it easy to create bar … Read more >>
When I first started using Matplotlib in Python more than a decade ago, one of the challenges I faced was how to visualize two datasets with different scales on the same chart. For example, I often had to compare U.S. sales revenue and customer satisfaction scores, both important metrics but measured in completely different units. … Read more >>
While working on a data visualization project in Python, I needed to invert the secondary Y-axis in a Matplotlib chart. At first, I thought it would be as simple as flipping the main Y-axis, but I quickly realized the secondary axis behaves differently. In this tutorial, I’ll walk you through how to invert the secondary … Read more >>
Working on a deep learning project where I needed to deploy an image classification model on a mobile device. The challenge was clear: I needed something lightweight yet powerful enough to handle complex image data efficiently. After exploring several architectures, I came across MobileViT, a mobile-friendly Transformer-based model that combines the strengths of Convolutional Neural … Read more >>
Radio buttons are essential form elements that allow users to select one option from multiple choices. As a web developer, you’ll often need to programmatically check or uncheck radio buttons using jQuery. This comprehensive tutorial will show you exactly how to set radio button checked states using jQuery, with practical examples and best practices. Basic … Read more >>
Recently, I was working on a computer vision project where I had to classify hundreds of product images like electronics, clothing, and groceries. While convolutional neural networks (CNNs) are the usual choice, I wanted to explore something different, modern MLP (Multi-Layer Perceptron) models that have been making waves in deep learning research. In this Python … Read more >>
