Matplotlib.axes.Axes.start_pan() in Python
• Last Updated : 21 Apr, 2020

Matplotlib is a library in Python and it is numerical – mathematical extension for NumPy library. The Axes Class contains most of the figure elements: Axis, Tick, Line2D, Text, Polygon, etc., and sets the coordinate system. And the instances of Axes supports callbacks through a callbacks attribute.

## matplotlib.axes.Axes.start_pan() Function

The Axes.start_pan() function in axes module of matplotlib library is called when a pan operation has started.

Syntax: Axes.start_pan(self, x, y, button)

Parameters: This method accept the following parameters that are described below:

• x, y: These parameter are the mouse coordinates in display coords.
• button: This parameter is the mouse button number:
• 1: LEFT
• 2: MIDDLE
• 3: RIGHT

Returns: This methos does not return any value.

Below examples illustrate the matplotlib.axes.Axes.start_pan() function in matplotlib.axes:

Example 1:

 `# Implementation of matplotlib function``import` `matplotlib.pyplot as plt``import` `numpy as np``  ` `np.random.seed(``10``*``*``7``)``data ``=` `np.random.normal(``0``, ``5``, ``100``)``  ` `fig, ax1 ``=` `plt.subplots()``val ``=` `ax1.violinplot(data)``ax1.start_pan(``1``, ``0``, ``3``)``   ` `ax1.set_title(``'matplotlib.axes.Axes.start_pan() Example'``)``plt.show()`

Output:

Example 2:

 `# Implementation of matplotlib function``import` `matplotlib.pyplot as plt``import` `numpy as np``   ` `geeks ``=` `np.array([``24.40``, ``110.25``, ``20.05``, ``                  ``22.00``, ``61.90``, ``7.80``, ``                  ``15.00``, ``22.80``, ``34.90``,``                  ``57.30``])``   ` `fig, ax ``=` `plt.subplots()``ax.acorr(geeks, maxlags ``=` `9``)`` ` `ax.set_ylabel(``'Y-axis'``)``ax.start_pan(``0``, ``0.6``, ``1``)``   ` `ax.set_title(``'matplotlib.axes.Axes.start_pan() Example'``)``plt.show()`
