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

importmatplotlib.pyplotasplt
importnumpyasnp
cms = cm * np.arange (0, 10, 2)
fig , axs = plt.subplots (2, 2, layout='constrained')
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(-1, 4) # 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 ()
