Notice how in this example, *par1* and *par2* are both obtained by calling ``twinx()``, which ties their x-limits with the host's x-axis. From there, each of those two axis behave separately from each other: different datasets can be plotted, and the y-limits are adjusted separately. Note that this approach uses the `mpl_toolkits.axes_grid1.parasite_axes`' `~mpl_toolkits.axes_grid1.parasite_axes.host_subplot` and `mpl_toolkits.axisartist.axislines.Axes`. An alternative approach using the `~mpl_toolkits.axes_grid1.parasite_axes`'s `~.mpl_toolkits.axes_grid1.parasite_axes.HostAxes` and `~.mpl_toolkits.axes_grid1.parasite_axes.ParasiteAxes` is the :doc:`/gallery/axisartist/demo_parasite_axes` example. An alternative approach using the usual Matplotlib subplots is shown in the :doc:`/gallery/ticks_and_spines/multiple_yaxis_with_spines` example. .. image:: /gallery/axisartist/images/sphx_glr_demo_parasite_axes2_001.png :alt: demo parasite axes2 :class: sphx-glr-single-img .. code-block:: default from mpl_toolkits.axes_grid1 import host_subplot from mpl_toolkits import axisartist import matplotlib.pyplot as plt host = host_subplot(111, axes_class=axisartist.Axes) plt.subplots_adjust(right=0.75) par1 = host.twinx() par2 = host.twinx() par2.axis["right"] = par2.new_fixed_axis(loc="right", offset=(60, 0)) par1.axis["right"].toggle(all=True) par2.axis["right"].toggle(all=True) p1, = host.plot([0, 1, 2], [0, 1, 2], label="Density") p2, = par1.plot([0, 1, 2], [0, 3, 2], label="Temperature") p3, = par2.plot([0, 1, 2], [50, 30, 15], label="Velocity") host.set_xlim(0, 2) host.set_ylim(0, 2) par1.set_ylim(0, 4) par2.set_ylim(1, 65) host.set_xlabel("Distance") host.set_ylabel("Density") par1.set_ylabel("Temperature") par2.set_ylabel("Velocity") host.legend() host.axis["left"].label.set_color(p1.get_color()) par1.axis["right"].label.set_color(p2.get_color()) par2.axis["right"].label.set_color(p3.get_color()) plt.show() .. _sphx_glr_download_gallery_axisartist_demo_parasite_axes2.py: .. only :: html .. container:: sphx-glr-footer :class: sphx-glr-footer-example .. container:: sphx-glr-download sphx-glr-download-python :download:`Download Python source code: demo_parasite_axes2.py ` .. container:: sphx-glr-download sphx-glr-download-jupyter :download:`Download Jupyter notebook: demo_parasite_axes2.ipynb ` .. only:: html .. rst-class:: sphx-glr-signature Keywords: matplotlib code example, codex, python plot, pyplot `Gallery generated by Sphinx-Gallery `_
