One of the libraries I keep coming back to for data visualization is Matplotlib. It’s flexible and widely used across industries in the USA, from finance to healthcare. But if you’ve ever created multiple plots in the same figure, you might have noticed how tricky it can be to get the spacing just right. That’s … Read more >>
One of the most useful tools I’ve used for data visualization is Matplotlib. When it comes to plotting time-series data, Matplotlib’s `plot_date` function stands out as an easy yet flexible way to visualize dates on the x-axis. In my experience, handling dates in plots can sometimes be tricky, especially when you want the x-axis to … Read more >>
Recently, I was working on a TypeScript project where I had to fetch user data from an object based on dynamic string IDs. In that process, I got a TypeScript compile error stating that we couldn’t index the object with a string. After searching for the solutions, I came to know that the issue was … Read more >>
Recently, while working on a TypeScript feature that involved updating specific fields on an object, I ran into a problem. I wanted to allow dynamic property access, but only for specific fields, and TypeScript wasn’t providing the safety as required. After searching for solutions, I found out that we can use the keyof operator along … Read more >>
