Have you ever encountered a problem with tight_layout() in your Python code? Specifically, have you encountered the issue where it ignores the figure suptitle? If so, you’re not alone. This issue has been a common headache for many users of the matplotlib library, and thankfully, there’s an explanation and solution for it.
Firstly, let’s understand what tight_layout() does. This function is designed to automatically adjust the padding between subplots so that they fit nicely within a figure. However, when a suptitle is added to the figure, the space allocated for it may get overridden by the layout algorithm, causing the suptitle to be cut off or squeezed.
So, why does this happen? The answer lies in the fact that tight_layout() uses the bbox_inches parameter to determine the size of the subplots. This parameter only considers the extents of the axes objects, but doesn’t take into account any additional elements in the figure, such as suptitles or legends. As a result, the layout algorithm may not allocate enough space for these elements.
Fortunately, there’s a workaround for this issue. Instead of using tight_layout(), you can manually adjust the spacing between subplots using subplots_adjust(). This function allows you to define the amount of space between the subplots and the suptitle, giving you more control over the layout of your figure. By taking this approach, you can ensure that your suptitle is not ignored and is displayed properly within your figure.
If you’ve been struggling with the frustrating issue of tight_layout() ignoring your figure suptitle, then this explanation and solution should help you overcome this challenge. So next time, instead of banging your head against the wall trying to adjust tight_layout(), try subplots_adjust() to get your desired layout.

Introduction
Python offers numerous packages that help in data visualization, and Matplotlib is one of the most popular among them. Data visualization is an essential part of data analysis and presentation. Matplotlib offers a wide range of options to create excellent figures and plots, but sometimes, errors occur in plotting. In this blog article, we discuss one such error – Figure suptitle ignored by tight_layout() – and why this error occurs despite providing a title.
The Error – Figure Suptitle Ignored by Tight_Layout()
Matplotlib provides us with a tight_layout() function that helps adjust the spacing between subplots and other plot elements. However, when using this function, the Figure suptitle, which is intended to work as the title of the entire figure, can be ignored. This often happens even when you provide the suptitle() function with a non-empty string.
Why Does This Error Occur?
The problem arises because of a conflict between the suptitle() and tight_layout() functions. Suptitle(), being a high-level method, adjusts the title’s location and size based on the size of the figure. On the other hand, tight_layout() calculates the spacing between the subplots based on the size of the parent container, which can override the adjustments made by the suptitle() function.
A Demo of The Problem
To see how this error occurs, let us take an example. Consider a 2×2 grid of plots, with a single suptitle for the entire figure. We create the plot using the following code snippet:
Now, let us try to use the tight_layout() function on this plot:
As we can see, the plot with a suptitle has become smaller and located such that only a part of the text is visible.
How To Overcome This Error?
To overcome this issue, we need to adjust the plot’s parameters (size and location) manually rather than letting them be adjusted by Matplotlib’s methods. To do this, we replace the suptitle() method with text(), which lets us place the text at any location within the figure and adjust its size as required. We also modify the Plotting snippet as follows:
It is now possible to use tight_layout() without worrying about losing the suptitle or text.
Comparison Between Suptitle() and Text() Methods
To understand the differences between the two methods, let us consider a comparison table:
| Method | Advantages | Disadvantages |
|---|---|---|
| suptitle() | Automatic placement based on the figure size | Position and size adjustment by other plots/margins may override the position of the title |
| text() | Complete control over positioning and size | Manual adjustments required for proper alignment |
Conclusion
In conclusion, we have seen why the error – Figure suptitle ignored by tight_layout() – occurs in Matplotlib while plotting. We also demonstrated how to resolve the error by replacing the suptitle() method with text(). We compared the advantages and disadvantages of both methods, which help us choose between them based on our requirements. Remember, Matplotlib provides us with several options for plotting customization, and it is essential to know when and how to use them.
Thank You for Visiting Our Blog!
We hope you found our article on the issue of Figure Suptitle Ignored by Tight_layout() informative and useful. In this article, we have discussed why certain figures with subplots may experience issues with tight_layout() when they have a suptitle.
One of the main takeaways from this article is that when using tight_layout(), it is best to have the figure without any suptitle. This is because suptitle takes up additional space which may lead to overlaps between the subplots. However, if you still want to include a suptitle in your figure, you can try using Constrained Layout instead of tight_layout().
Once again, we appreciate you taking the time to read our blog. We hope this article has been able to solve your query regarding Figure Suptitle Ignored by Tight_layout().

People Also Ask about Figure suptitle ignored by tight_layout() – Here’s why:
- What is Figure suptitle?
- What does ignored by tight_layout() mean?
- How can I fix Figure suptitle ignored by tight_layout()?
Figure suptitle is a function in Matplotlib that allows you to add a title to your figure. It is usually used to give a descriptive title to your plot.
Tight_layout() is another function in Matplotlib that automatically adjusts the padding and spacing of a figure to fit all the subplots within it. When a suptitle is added to the figure, it can sometimes cause tight_layout() to ignore the space needed for the title, resulting in a squished or cut-off figure.
- You can manually adjust the spacing around the figure using subplots_adjust() after adding the suptitle.
- You can also increase the height of the figure to make room for the suptitle by adjusting the figsize parameter when creating the figure.
- If neither of these solutions work, you can try using the constrained_layout option in Matplotlib, which automatically adjusts the spacing of subplots and titles to avoid overlapping or squishing.
One way to prevent this issue is to add the suptitle before creating the subplots, as this gives tight_layout() the opportunity to adjust the spacing accordingly. Another solution is to use the set_title() function on each individual subplot instead of a suptitle.
