Do you want to create static, animated, and interactive visualizations in Python? Then, learn about the Matplotlib library. Check out all our practical Matplotlib tutorials with real examples.
When I first started working with Matplotlib in Python, I often needed to create bar charts where the x-axis represented dates. I’ve worked on multiple projects in the USA where date-based bar charts were essential. For example, tracking daily sales, visualizing monthly website traffic, or analyzing yearly energy consumption. In this tutorial, I’ll walk you … Read more >>
I have been working with Python and data visualization for more than a decade. I have often needed to create quick bar charts directly from Pandas DataFrames. At first, I used to export my data to Excel and create charts there. But once I realized how powerful Matplotlib is, I switched to plotting directly in … Read more >>
I have been working with Python for many years, and one of the most common tasks I face is creating quick visualizations from data. Many times, the data I receive is in the form of a Python dictionary. Instead of converting it into a DataFrame or CSV, I often directly plot it using Matplotlib bar … Read more >>
I was working on a Python project where I had to visualize sales data for different states in the USA. The dataset contained multiple categories, and I wanted each bar in my chart to stand out with its own unique color. At first, I thought Matplotlib would have a quick one-click option to do this. … Read more >>
When I first started working with Matplotlib in Python, I often added extra lines to my plots to highlight thresholds or averages. But sometimes, I needed to remove those horizontal lines later. At first, I thought there would be a direct to button “remove line”, but Matplotlib doesn’t work that way. Instead, you need to … Read more >>
As part of a Python project, I wanted to highlight a specific threshold in my chart. I needed to draw a horizontal line and add text to explain what that line represented. The problem was that while drawing a horizontal line in Matplotlib is easy, adding text in the right place can be tricky for … Read more >>
To show only horizontal grid lines in Matplotlib, pass axis=”y” to grid: Add ax.set_axisbelow(True) with it. Without that, gridlines are drawn on top of your bars and markers, which isn’t what anyone wants. Every plot below is a real Matplotlib window on Python 3.12.5, Matplotlib 3.11.2. Showing horizontal grid lines only The axis argument decides … Read more >>
Recently, I was working on a Python project where I had to visualize some experimental data with error bars and also emphasize a reference value using a horizontal line. At first, I thought Matplotlib might have a built-in option for combining error bars with horizontal lines. But after a bit of exploration, I realized we … Read more >>
While I was working on a Python project, I needed to highlight certain thresholds across multiple charts. I was using Matplotlib subplots to show different datasets side by side, and I wanted to add a horizontal line in each subplot to mark a reference value. At first, I thought there would be a quick one-click … Read more >>
When I first started working with Python for data visualization, I often needed to highlight thresholds or reference levels in my charts. One of the simplest ways to do this is by adding horizontal lines. I’ve used horizontal lines in Matplotlib countless times. Whether I was analyzing stock prices, visualizing air quality data, or building … Read more >>
