Matplotlib.axis.Axis.update_units() function in Python Last Updated : 21 Dec, 2022 Comments Improve Suggest changes Like Article Like Report Matplotlib is a library in Python and it is numerical – mathematical extension for NumPy library. It is an amazing visualization library in Python for 2D plots of arrays and used for working with the broader SciPy stack. Matplotlib.axis.Axis.update_units() Function The Axis.update_units() function in axis module of matplotlib library is used to introspect data for units converter and update the axis.converter instance if necessary. Syntax: Axis.update_units(self, data) Parameters: This method accepts the following parameters. data: This parameter is the data to be update. Return value: This method return True if data is registered for unit conversion. Below examples illustrate the matplotlib.axis.Axis.update_units() function in matplotlib.axis: Example 1: Python3 # Implementation of matplotlib function from matplotlib.axis import Axis import matplotlib.pyplot as plt import numpy as np np.random.seed(10**7) geeks = np.random.randn(100) fig, ax = plt.subplots() ax.acorr(geeks, usevlines = True, normed = True, maxlags = 80, lw = 3) ax.grid(True) prop = {'xticks': np.array([-100., -50., 0., 50., 100.]), 'yticks': np.array([-0.2, 0.2, 0.6, 1., 1.4]), 'ylabel': None, 'xlabel': None} ax.update(prop) w = Axis.update_units(ax.xaxis,[1,2,3,4,5]) print(w) fig.suptitle("""matplotlib.axis.Axis.update_units() function Example\n""", fontweight ="bold") plt.show() Output: False Example 2 Python3 # Implementation of matplotlib function from matplotlib.axis import Axis import numpy as np import matplotlib.pyplot as plt xx = np.random.rand(16, 30) fig, ax = plt.subplots() m = ax.pcolor(xx) m.set_zorder(-20) w = Axis.update_units(ax.xaxis,[1,2,3,4,5]) print(w) fig.suptitle("""matplotlib.axis.Axis.update_units() function Example\n""", fontweight ="bold") plt.show() Output: False Comment More infoAdvertise with us Next Article Matplotlib.axis.Axis.update_units() function in Python S SHUBHAMSINGH10 Follow Improve Article Tags : Python Python-matplotlib Matplotlib-Axis Class Practice Tags : python Similar Reads Matplotlib.axis.Axis.update() function in Python Matplotlib is a library in Python and it is numerical – mathematical extension for NumPy library.
