How to force Matplotlib to show the values on X-axis as integers?

To force matplotlib to show the values on X-axis as integers, we can take the following steps −

• Set the figure size and adjust the padding between and around the subplots.
• Create two lists, x and y, of data points.
• Plot x and y using plot() method.
• Make a new list for only integers tick on X-axis. Use math.floor() and math.ceil() to remove the decimals and include only integers in the list.
• Set x and y labels.
• Set the title of the figure.
• To display the figure, use show() method.

Example

import math from matplotlib import pyplot as plt plt.rcParams["figure.figsize"] = [7.50, 3.50] plt.rcParams["figure.autolayout"] = True y = [0.17, 1.17, 2.98, 3.15, 4.11, 5.151] x = [1.0, 1.75, 2.90, 3.15, 4.50, 5.50] plt.plot(x, y) new_list = range(math.floor(min(x)), math.ceil(max(x))+1) plt.xticks(new_list) plt.xlabel("X-axis ") plt.ylabel("Y-axis ") plt.title("Only Integers on the X-axis") plt.show()
