=========================
Simple Plotting of Fronts
=========================
This uses MetPy's path effects for matplotlib that can be used to represent a line as a
traditional front. This example relies on already having location information for the
boundaries you would like to plot.

Define some synthetic points to represent the low pressure system and its frontal boundaries.

Draw the low as an "L" using matplotlib's `text()` method, then plot the fronts as
standard lines, but add our path effects.

    fig, ax = plt.subplots(figsize=(8, 8), dpi=150)
    ax.text(low_lon, low_lat, 'L', color='red', size=30,
            horizontalalignment='center', verticalalignment='center')
    ax.plot(cold_lon, cold_lat, 'blue', path_effects=[ColdFront(size=8, spacing=1.5)])
    ax.plot(warm_lon, warm_lat, 'red', path_effects=[WarmFront(size=8, spacing=1.5)])
