          alignment_period: (Optional str) E.g., "120s". The size of each point's
            bucket of data. If None is provided, each point in the graph will refer
            to a moment in time rather than a bucket of time. Min is 60s.

            for each series.
          major_formatter: (Optional matplotlib.Formatter) The formatter for each
            major tick mark's x-axis time label. Defaults to one that turns an X point
            into HH:MM e.g., "17:35".
