def drawAsInfinite(requestContext, seriesList):
    """
    Takes one metric or a wildcard seriesList.
    If the value is zero, draw the line at 0. If the value is above zero, draw
    the line at infinity. If the value is null or less than zero, do not draw
    the line.

    Useful for displaying on/off metrics, such as exit codes. (0 = success,
    anything else = failure.)

    Example::

        drawAsInfinite(Testing.script.exitCode)

    """
    for series in seriesList:
        series.options['drawAsInfinite'] = True
        series.name = 'drawAsInfinite(%s)' % series.name
    return seriesList
