Matplotlib is a library in Python and it is numerical – mathematical extension for NumPy library. Pyplot is a state-based interface to a Matplotlib module which provides a MATLAB-like interface.
matplotlib.pyplot.ylim() Function
The ylim() function in pyplot module of matplotlib library is used to get or set the y-limits of the current axes.
Syntax: matplotlib.pyplot.ylim(*args, **kwargs)
Parameters: This method accept the following parameters that are described below:
- bottom: This parameter is used to set the ylim to bottom.
- top: This parameter is used to set the ylim to top.
- **kwargs: This parameter is Text properties that is used to control the appearance of the labels.
Returns: This returns the following:
- bottom, top :This returns the tuple of the new y-axis limits.
Below examples illustrate the matplotlib.pyplot.ylim() function in matplotlib.pyplot:
Example #1:
# Implementation of matplotlib functionimport matplotlib.pyplot as pltimport numpy as np ax = plt.subplot(111) t = np.arange(0.0, 5.0, 0.01)s = np.cos(2 * np.pi * t)line, = plt.plot(t, s, lw = 2) plt.annotate('local max', xy =(2, 1), xytext =(3, 1.5), arrowprops = dict(facecolor ='black', shrink = 0.05), ) plt.ylim(-2, 2)plt.title(" matplotlib.pyplot.ylim() Example")plt.show() |
Output:
Example #2:
# Implementation of matplotlib functionimport matplotlib.pyplot as pltimport numpy as np np.random.seed(9680801) mu, sigma = 50, 13x = mu + sigma * np.random.randn(10000) # the histogram of the datan, bins, patches = plt.hist(x, 50, density = True, facecolor ='g', alpha = 0.75) plt.xlabel('No of Users in K')plt.title('Histogram of IQ')plt.text(50, .035, r'$\mu = 50,\\ \sigma = 13$') plt.xlim(-10, 110)plt.ylim(0, 0.04) plt.grid(True)plt.title(" matplotlib.pyplot.ylim() Example") plt.show() |
Output:
