.. _examples-meteoinfolab-plot_types-polar: ******************* Polar plot ******************* Polar axes can be created using ``axes(polar=True)`` function. Then use ``plot``, ``bar`` and other plot functions to plot the data in the polar axes. Plot a line in a polar axes :: r = arange(0, 2, 0.01) theta = 2 * pi * r ax = axes(position=[0.1,0.1,0.8,0.8], polar=True) plot(theta, r, color='b', linewidth=2) title('Polor chart example') antialias(True) .. image:: ../../../_static/news/mi_1.4.2_lab_polar_plot.png Plot bars in a polar axes :: # Compute pie slices N = 40 theta = linspace(0.0, 2 * pi, N, endpoint=False) radii = 10 * random.rand(N) cols = makecolors(N, alpha=0.5) axes(polar=True) bars = bar(theta, radii, theta[1]-theta[0], bottom=1, color=cols, edgecolor='gray') antialias(True) .. image:: ../../../_static/news/mi_1.4.2_lab_polar_bar.png
