# Unit handling

The example below shows support for unit conversions over masked arrays.

This example requires `basic_units.py`

    import numpy as np
    import matplotlib.pyplot as plt
    from basic_units import secs, hertz, minutes

    # create masked array
    data = (1, 2, 3, 4, 5, 6, 7, 8)
    mask = (1, 0, 1, 0, 0, 0, 1, 0)
    xsecs = secs * np.ma.MaskedArray(data, mask, float)

    fig, (ax1, ax2, ax3) = plt.subplots(nrows=3, sharex=True)
    ax1.scatter(xsecs, xsecs)
    ax1.yaxis.set_units(secs)
    ax1.axis([0, 10, 0, 10])

    ax2.scatter(xsecs, xsecs, yunits=hertz)
    ax2.axis([0, 10, 0, 1])

    ax3.scatter(xsecs, xsecs, yunits=hertz)
    ax3.yaxis.set_units(minutes)
    ax3.axis([0, 10, 0, 1])

    fig.tight_layout()
    plt.show()
