How to Close an Embed Graph in Tkinter with Matplotlib

If you're developing an application using Tkinter and Matplotlib, you might find yourself asking, "How can I close an embedded graph?" This can be a common issue for beginners who want to manage the display of their data visualizations effectively. In this guide, we'll explore how to clear an embedded graph in Tkinter rather than closing it completely, which is actually what most users want.

Understanding the Concept

In applications where you embed graphs within a GUI (Graphical User Interface), it's often necessary not to completely shut down the graph but to remove the current plot, so it's ready to display new data. This is particularly useful in scientific applications or dashboards where data changes frequently.

Here’s a breakdown of what you need to do to clear an embedded graph using Matplotlib in conjunction with a Tkinter interface.

Solution Overview

Instead of trying to "close" a graph, the solution lies in clearing the graph. This can be achieved using the method fig.clear() which prepares your figure for new plotting.

Step-by-Step Implementation

Initial Setup: Make sure you have imported the necessary libraries: matplotlib, tkinter, and others required for your application.

Create the Tkinter Window and Canvas: Set up your Tkinter window and the canvas where your Matplotlib figure will reside.

Define Functions to Plot Data: Write functions that will handle the plotting of your specific data sets. Each of these functions will incorporate the fig.clear() command to reset the figure.

Implement Buttons: Create buttons for user interaction which will trigger the plotting functions.

Sample Code Implementation

Here’s a refined version of your original code where the graph is properly cleared:

Conclusion

By using fig.clear(), you make it easy to update your graphs without closing the Tkinter window or the Matplotlib figure entirely. This approach is not only effective but also enhances user experience in applications where data visualizations are frequently updated.

Feel free to adapt the functions for male or combined fertility data, and remember that interactive elements enhance the usability of any graphical application!

With this understanding, you can manage your embedded graphs seamlessly—no need for that clunky close button!
