.. _sphx_glr_gallery_units_units_sample.py: ====================== 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. .. only:: builder_html This example requires :download:`basic_units.py ` .. image:: /gallery/units/images/sphx_glr_units_sample_001.png :align: center .. code-block:: python from basic_units import cm, inch import matplotlib.pyplot as plt import numpy as np cms = cm * np.arange(0, 10, 2) fig = plt.figure() ax1 = fig.add_subplot(2, 2, 1) ax1.plot(cms, cms) ax2 = fig.add_subplot(2, 2, 2) ax2.plot(cms, cms, xunits=cm, yunits=inch) ax3 = fig.add_subplot(2, 2, 3) ax3.plot(cms, cms, xunits=inch, yunits=cm) ax3.set_xlim(3, 6) # scalars are interpreted in current units ax4 = fig.add_subplot(2, 2, 4) ax4.plot(cms, cms, xunits=inch, yunits=inch) ax4.set_xlim(3*cm, 6*cm) # cm are converted to inches plt.show() **Total running time of the script:** ( 0 minutes 0.079 seconds) .. only :: html .. container:: sphx-glr-footer .. container:: sphx-glr-download :download:`Download Python source code: units_sample.py ` .. container:: sphx-glr-download :download:`Download Jupyter notebook: units_sample.ipynb ` .. only:: html .. rst-class:: sphx-glr-signature `Gallery generated by Sphinx-Gallery `_
