# Controlling style of text and labels using a dictionary

This example shows how to share parameters across many text objects and labels by creating a dictionary of options passed across several functions.

    import numpy as np
    import matplotlib.pyplot as plt

    font = {'family': 'serif',
            'color':  'darkred',
            'weight': 'normal',
            'size': 16,
            }

    x = np.linspace(0.0, 5.0, 100)
    y = np.cos(2*np.pi*x) * np.exp(-x)

    plt.plot(x, y, 'k')
    plt.title('Damped exponential decay', fontdict=font)
    plt.text(2, 0.65, r'$\cos(2 \pi t) \exp(-t)$', fontdict=font)
    plt.xlabel('time (s)', fontdict=font)
    plt.ylabel('voltage (mV)', fontdict=font)

    # Tweak spacing to prevent clipping of ylabel
    plt.subplots_adjust(left=0.15)
    plt.show()
