How to Set X-Axis Values in Matplotlib in Python? Last Updated : 13 Sep, 2022 Comments Improve Suggest changes Like Article Like Report In this article, we will be looking at the approach to set x-axis values in matplotlib in a python programming language. The xticks() function in pyplot module of the Matplotlib library is used to set x-axis values. Syntax: matplotlib.pyplot.xticks(ticks=None, labels=None, **kwargs) xticks() function accepts the following parameters: ParametersDescriptionticksList of xticks locations.OptionalPassing an empty list will remove all the xticks.labelsList of labels to place at given ticks location.Optional**kwargsText properties used to control the appearance of labels. Returns: xticks() function returns following values: locs: List of xticks location.labels: List of xlabel text location. Example #1 : In this example, we will be setting up the X-Axis Values in Matplotlib using the xtick() function in the python programming language. Python3 # Python program to set x-axis values in matplotlib import matplotlib.pyplot as plt # x-axis and y-axis values for plotting x = [1, 2, 3, 4, 5, 6] y = [3, 1, 4, 5, 3, 6] # labels for x-asix labels = ['A', 'B', 'C', 'D', 'E', 'F'] # Plotting x-axis and y-axis plt.plot(x, y) # naming of x-axis and y-axis plt.xlabel("X-Axis") plt.ylabel("Y-Axis") # naming the title of the plot plt.title("Set X-Axis Values in Matplotlib") # setting x-axis values plt.xticks(x, labels) plt.show() Output: Example #2: In this example, we will use the rotation argument to accept rotation value in degree and it will rotate labels in the clockwise direction by specified degree. Python3 # Python program to set x-axis values in matplotlib import matplotlib.pyplot as plt # x-axis and y-axis values for plotting x = [1, 2, 3, 4, 5, 6] y = [3, 1, 4, 5, 3, 6] # labels for x-asix labels = ['Label1', 'Label2', 'Label3', 'Label4', 'Label5', 'Label6'] # Plotting x-axis and y-axis plt.plot(x, y) # naming of x-axis and y-axis plt.xlabel("X-Axis") plt.ylabel("Y-Axis") # naming the title of the plot plt.title("Set X-Axis Values in Matplotlib") # setting x-axis values and specifying rotation # for the labels in degrees plt.xticks(x, labels, rotation=45) plt.show() Output: Comment More infoAdvertise with us Next Article How to Set X-Axis Values in Matplotlib in Python?

Matplotlib sets the default range of the axis by finding extreme values (i.e. minimum and maximum) on that axis. However, to get a better view of data sometimes the Pyplot module is used to set axis ranges of the graphs according to the requirements in Matplotlib.
