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 methods does not return any value.
Below examples illustrate the matplotlib.axes.Axes.start_pan() function in matplotlib.axes:
Example 1:
Python3
# Implementation of matplotlib functionimport matplotlib.pyplot as pltimport 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:
Python3
# Implementation of matplotlib functionimport matplotlib.pyplot as pltimport numpy as np neveropen = 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(neveropen, 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() |
Output:
