    A linePlusBarChart Chart is a type of chart which displays information
    as a series of data points connected by straight line segments
    and with some series with rectangular bars with lengths proportional
    to the values that they represent.

    Python example::

        from nvd3 import linePlusBarChart
        chart = linePlusBarChart(name="linePlusBarChart",
                             width=500, height=400, x_axis_format="%d %b %Y",
                             x_is_date=True, focus_enable=True,
                             yaxis2_format="function(d) { return d3.format(',0.3f')(d) }")

        xdata = [1338501600000, 1345501600000, 1353501600000]
        ydata = [6, 5, 1]
        y2data = [0.002, 0.003, 0.004]

        extra_serie = {"tooltip": {"y_start": "There are ", "y_end": " calls"},
                       "date_format": "%d %b %Y %H:%S" }
        chart.add_serie(name="Serie 1", y=ydata, x=xdata, extra=extra_serie,
                        bar=True)

        extra_serie = {"tooltip": {"y_start": "There are ", "y_end": " min"}}
        chart.add_serie(name="Serie 2", y=y2data, x=xdata, extra=extra_serie)
        chart.buildhtml()
        print(chart.content)

    Note that in case you have two data serie with extreme different numbers,
    that you would like to format in different ways,
    you can pass a keyword *yaxis1_format* or *yaxis2_format* when
    creating the graph.

    In the example above the graph created presents the values of the second
    data series with three digits right  of the decimal point.
