def plots(self):
        """
        The sequence of plots in this chart. A plot, called a *chart group*
        in the Microsoft API, is a distinct sequence of one or more series
        depicted in a particular charting type. For example, a chart having
        a series plotted as a line overlaid on three series plotted as
        columns would have two plots; the first corresponding to the three
        column series and the second to the line series. Plots are sequenced
        in the order drawn, i.e. back-most to front-most. Supports *len()*,
        membership (e.g. ``p in plots``), iteration, slicing, and indexed
        access (e.g. ``plot = plots[i]``).
