Inches and Centimeters#
The example illustrates the ability to override default x and y units (ax1) to
inches and centimeters using the xunits and yunits parameters for the
plot
function. Note that conversions are applied to get numbers
to correct units.
This example requires basic_units.py
![units sample](../../_images/sphx_glr_units_sample_001.png)
from basic_units import cm, inch
import matplotlib.pyplot as plt
import numpy as np
cms = cm * np.arange(0, 10, 2)
fig, axs = plt.subplots(2, 2)
axs[0, 0].plot(cms, cms)
axs[0, 1].plot(cms, cms, xunits=cm, yunits=inch)
axs[1, 0].plot(cms, cms, xunits=inch, yunits=cm)
axs[1, 0].set_xlim(3, 6) # scalars are interpreted in current units
axs[1, 1].plot(cms, cms, xunits=inch, yunits=inch)
axs[1, 1].set_xlim(3*cm, 6*cm) # cm are converted to inches
plt.show()
