Matplotlib Tick Label Fontweight Is Limited To A Few Options

See the following code import numpy as np import matplotlib.pyplot as plt x = np.linspace(0.0001, 30, 1000) y = np.sin(x)/x fig, ax = plt.subplots(1, 1) ax.plot(x, y) ax.tick_par

Solution 1:

Normally, a font only has limited number of font weight, such as Regular, Medium, Bold, etc. The font weights are not infinite.

There is correspondence between the numeric value and finite font weight. For more details, see here.
