Introduction
Matplotlib is a plotting library for the Python programming language and its pyplot module is a collection of functions that provide a convenient interface for creating graphics. One of the challenges when using Matplotlib is clearing previous plots. In this article, we will explore different ways to clear previous plots on Matplotlib.Pyplot.
Clearing Previous Plots Using clf()
The `clf()` function clears the current figure, it can be called multiple times to clear each time a new plot is created. This function is often used when creating new plots without wanting the previous ones to interfere.
| Pros | Cons |
|---|---|
| Quick way to clear previous plots | Removes all elements and resets the figure to a blank canvas |
| Cannot undo the clearing process |
In my opinion, clf() is a good option when you need to create a new plot quickly without any remnants of previous plots.
Clearing Previous Plots Using cla()
The `cla()` function clears the current axes, however, it does not remove the current figure from the canvas. Calling this function can make it easy to keep the current figure structure but change the content of the plot.
| Pros | Cons |
|---|---|
| Does not erase the current figure structure | Only clears the current axes, not the entire figure |
| Cannot be used to clear multiple axes or subplots at once |
In my opinion, cla() is a good option when you need to just clear the plot elements within an axis without removing the entire axis structure.
Clearing Previous Plots Using close()
The `close()` function destroys the current figure window and frees all memory associated with it. This function should be used carefully as it will completely remove the entire plot window and prevent any further manipulation of the plot.
| Pros | Cons |
|---|---|
| Completely removes the plot window freeing up memory | Cannot undo the closing of the figure window |
| Cannot selectively remove individual plot elements but clears everything |
In my opinion, close() is a good option when you need to completely remove a plot window or if you have too many plot windows open and want to free up memory.
Clearing Previous Plots Using clf(), cla() and close()
When used in combination, clf(), cla() and close() functions provide a powerful clearing effect for creating new plots from scratch. These functions together are useful for complex plot applications where selectively clearing plot elements, clearing a single plot axes or completely destroying plot windows is necessary.
| Pros | Cons |
|---|---|
| Provides control over clearing plot elements, plot axes or plot windows | Can be complicated for simple plot applications |
| Requires multiple function calls to achieve the desired result |
In my opinion, using a combination of clf(), cla() and close() is a good option when you need fine-grained control over clearing plot elements or deleting entire plot windows.
Conclusion
In conclusion, all of the functions we’ve discussed have their merits and drawbacks depending on the use case. clf() provides quick clearing of the current figure but removes all elements from the entire figure, requiring you to start over from scratch. cla() provides you with control over the individual axes while still preserving the overall structure of a figure. Close() can give you ultimate control to destroy your figures as you please, allowing you to not run out of memory. Using a combination of clf(), cla(), and close() can provide with you just the right amount of power to create robust plots with fine-grained clearing ability.

Numbered list:
- How can I clear the previous plot in Matplotlib.Pyplot?
- Is it possible to remove all the plotted data from a figure?
- What is the function to clear a figure in Matplotlib.Pyplot?
To clear the previous plot in Matplotlib.Pyplot, you can use the clf() function. This function clears the current figure and releases all memory associated with the previous plot. For example, you can call plt.clf() before plotting a new set of data to ensure that there are no remnants of the previous plot.
Yes, it is possible to remove all the plotted data from a figure in Matplotlib.Pyplot. To do this, you can call the cla() function, which clears the axis of the current figure. This function removes all the plotted data and resets the axis limits to their default values. You can use this function to start a new plot from scratch.
The function to clear a figure in Matplotlib.Pyplot is clf(). This function clears the entire figure and removes all the plotted data. It is also important to note that calling this function releases all memory associated with the previous plot, which can be useful for optimizing memory usage in larger scripts.
