To set the unit length of an axis in Matplotlib, we can use xlim or ylim with scale factor of the axes, i.e., of unit length times.
steps
Set the figure size and adjust the padding between and around the subplots.
Create x and y data points using numpy.
Plot the x and y data points using plot() method.
Get the x and y axes, limit range.
Use xlim and ylim methods to set the unit length scale.
To display the figure, use show() method.
Example
import matplotlib.pyplot as plt import numpy as np plt.rcParams["figure.figsize"] = [7.50, 3.50] plt.rcParams["figure.autolayout"] = True x = np.linspace(1, 10, 100) y = np.log(x) plt.plot(x, y) axis_scale = 2 xmin, xmax = plt.xlim() ymin, ymax = plt.ylim() plt.xlim(xmin * axis_scale, xmax * axis_scale) plt.ylim(ymin * axis_scale, ymax * axis_scale) plt.show()
