# Difference Between cla(), clf() and close() Methods in Matplotlib

• Last Updated : 13 Jan, 2021

Prerequisites: Matplotlib

Matplotlib is a library in Python. It is a mathematical extension of Numpy Library. It is a comprehensive library for creating static, animated, and interactive visualizations in Python. Pyplot is a state-based interface to a Matplotlib module. The Pyplot can create many types of plot such as line graph, bar graph, histogram etc.

The cla(), clf() and close() are different methods/functions of Matplotlib. The difference between them is as follows:

cla(): This method in the pyplot module of the matplotlib library is used to clear the current axes.

Syntax:

`matplotlib.pyplot.cla()`

Example :

## Python3

 `import` `numpy as np``import` `matplotlib.pyplot as plt`` ` `t ``=` `np.linspace(``0.0``, ``2.0``, ``401``)``s ``=` `np.sin(``2` `*` `np.pi ``*` `t)`` ` `fig, [ax, ax1] ``=` `plt.subplots(``2``, ``1``)`` ` `ax.set_ylabel(``'y-axis'``)``ax.plot(t, s)``ax.grid(``True``)`` ` `ax1.set_ylabel(``'y-axis'``)``ax1.set_xlabel(``'x-axis'``)``ax1.plot(t, s)``ax1.grid(``True``)``# Function call``ax1.cla()`` ` `fig.suptitle(``'matplotlib.pyplot.cla Example'``)``plt.show()`

Output: The subplot ax1 content is cleared.

clf(): The method in the pyplot module of the matplotlib library is used to clear the entire current figure. It even clears the subplot. It leaves the window space open so that it can be reused by other plots.

Syntax:

`matplotlib.pyplot.clf()`

Example:

## Python3

 `import` `numpy as np``import` `matplotlib.pyplot as plt`` ` `t ``=` `np.linspace(``0.0``, ``2.0``, ``201``)``s ``=` `np.sin(``2` `*` `np.pi ``*` `t)`` ` `fig, [ax, ax1] ``=` `plt.subplots(``2``, ``1``)`` ` `ax.set_ylabel(``'y-axis'``)``ax.plot(t, s)``ax.grid(``True``)`` ` `ax1.set_ylabel(``'y-axis'``)``ax1.set_xlabel(``'x-axis'``)``ax1.plot(t, s)``ax1.grid(``True``)`` ` `# Func. call``plt.clf()`` ` `fig.suptitle(``'matplotlib.pyplot.clf Example'``)``plt.show()`

Output: The clf() function cleared the entire figure and only space is left.

close(): The method in the pyplot module of the matplotlib library is used to close the window of the plot. By default, it closes the current window. Since the window is closed there will no output in this method.

Syntax:

`matplotlib.pyplot.close()`

Example:

## Python3

 `import` `numpy as np``import` `matplotlib.pyplot as plt`` ` `t ``=` `np.linspace(``0.0``, ``2.0``, ``201``)``s ``=` `np.sin(``2` `*` `np.pi ``*` `t)`` ` `fig, [ax, ax1] ``=` `plt.subplots(``2``, ``1``)`` ` `ax.set_ylabel(``'y-axis'``)``ax.plot(t, s)``ax.grid(``True``)`` ` `ax1.set_ylabel(``'y-axis'``)``ax1.set_xlabel(``'x-axis'``)``ax1.plot(t, s)``ax1.grid(``True``)`` ` `# Function call``plt.close()`` ` `fig.suptitle(``'matplotlib.pyplot.close Example'``)``plt.show()`
