Use plotly to create bar charts, histograms, scatter plots, bubble chart, and box plots and arrange these with subplots — Now that you have some background in using the plotly package (if you want a good introduction, you can read a previous article that I wrote), you may want to expand some of the plotting options that you have. In this post, I will demonstrate some of the other basic…

Easily build interactivity into your plots with similar customization to what you are used to from matplotlib — Some of the first articles I wrote on this platform were a series of tutorials about matplotlib, an incredible Python visualization library that I used extensively in grad school, and can be customized to no end to create beautiful figures. As a data visualization enthusiast, I am always looking for…

Use GitHub Actions to automate workflows and run and update results from scripts and notebooks — Let’s say that we have done some cool data analysis on a data stream that updates periodically, for example sports statistics or current weather conditions. Now, we add our code to version control on GitHub, but it would be really cool if we could get it to update with newer…

Methods to analyze multiple time-series signals that occur over the same time period but have different timestamps and time spacings — Say we have the following scenario — we have two different sensors that are measuring the current and voltage across a battery pack. Now, we want to do some basic analysis of these signals, namely look at the power consumed over time (which is equal to the current times voltage)…

Use gridspec to layout your figure without the need to export multiple plots and use another program to put them together — Publication figures typically require multiple plots placed into a panelled layout to tell a story. A simple drag-and-drop method to do this could be to individually create each plot, and then use either an image-editing program or even Powerpoint to arrange plots into a full figure and save as one…

Share your work with a simple and interactive web application — Say you’ve written a really cool script in Python to do some interesting data analysis and now you want to demonstrate it to others. Chances are, sending over a .py file and asking others to run it, or demonstrating yourself running it on the command line won’t have the same…

Ever felt like learning a new programming language? Go is a great choice! — I’ve recently heard a lot of buzz about proramming in Go and it piqued my curiousity. Proponents of Go laud it’s simplicity, concurrency, and performance — having basically been solely a Python programmer for the last few years, I wanted to try to get started with Go myself. Through learning…

Create a simple image classifier with neural networks in minutes! — Deep learning, a subset of machine learning that deals with artificial neural networks, has shown to be extremely powerful at image classification. Despite the mathematical rigor of the inner workings of these algorithms, Python libraries such as keras make these problems approachable to all of us. In this article, I…

Use a GUI-based program to generate reproducible Python plot scripts — A couple of months ago, I wrote an extensive article on generating scientific publication plots with Python. Recently, I discovered this incredible new package called Pylustrator, which greatly simplifies the process of making multi-panel figures without the need to fiddle with axes sizes. The package also then generates Python code…
