.. _units-bar_demo2: units example code: bar_demo2.py ================================ .. plot:: /home/tcaswell/source/p/matplotlib/doc/mpl_examples/units/bar_demo2.py :: """ plot using a variety of cm vs inches conversions. The example shows how default unit instrospection works (ax1), how various keywords can be used to set the x and y units to override the defaults (ax2, ax3, ax4) and how one can set the xlimits using scalars (ax3, current units assumed) or units (conversions applied to get the numbers to current units) """ import numpy as np from basic_units import cm, inch import matplotlib.pyplot as plt cms = cm * np.arange(0, 10, 2) bottom = 0*cm width = 0.8*cm fig = plt.figure() ax1 = fig.add_subplot(2, 2, 1) ax1.bar(cms, cms, bottom=bottom) ax2 = fig.add_subplot(2, 2, 2) ax2.bar(cms, cms, bottom=bottom, width=width, xunits=cm, yunits=inch) ax3 = fig.add_subplot(2, 2, 3) ax3.bar(cms, cms, bottom=bottom, width=width, xunits=inch, yunits=cm) ax3.set_xlim(2, 6) # scalars are interpreted in current units ax4 = fig.add_subplot(2, 2, 4) ax4.bar(cms, cms, bottom=bottom, width=width, xunits=inch, yunits=inch) #fig.savefig('simple_conversion_plot.png') ax4.set_xlim(2*cm, 6*cm) # cm are converted to inches plt.show() Keywords: python, matplotlib, pylab, example, codex (see :ref:`how-to-search-examples`)
