def lineWidth(requestContext, seriesList, width):
    """
    Takes one metric or a wildcard seriesList, followed by a float F.

    Draw the selected metrics with a line width of F, overriding the default
    value of 1, or the &lineWidth=X.X parameter.

    Useful for highlighting a single metric out of many, or having multiple
    line widths in one graph.

    Example::

        &target=lineWidth(server01.instance01.memory.free,5)
