get all values of data points above the line chart

Hello,

Currently I am working on a mixed chart. Below find the first part of my
chart:

   drawing = Drawing(250, 175)
   data = [ (3,3,3,10,14,1,1,1,11,13,12,7)  ]  # total

    lc = HorizontalLineChart()
    lc.x = 40
    lc.y = -175
    lc.height = 225
    lc.width = 610
    lc.data = data
    lc.joinedLines = 1
    lc.inFill = 1

    lc.categoryAxis.categoryNames =
['0:00','2:00','4:00','6:00','8:00','10:00','12:00','14:00','16:00','18:00','20:00','22:00']
    lc.valueAxis.valueMin = 0
    lc.valueAxis.valueMax = 15
    lc.lineLabelFormat = '%0.0f'
    lc.lineLabelNudge = 2
    lc.lines[0].strokeColor= colors.beige
    drawing.add(lc)

Since I would like to add the below part, the values of the above part
should all stand above the line to be visible. I tried to play with
'lineLabelNudge', but the best I can do is to make them all half visible.
Do you have any suggestions of how to solve that ?
Thansks in advance,
Helga

    bc.x = lc.x
    bc.y = lc.y
    bc.height = lc.height
    bc.width = lc.width
    bc.data = data3
    bc.categoryAxis.style = 'stacked'
    bc.valueAxis.valueMin = 0
    bc.valueAxis.valueMax = lc.valueAxis.valueMax
    bc.categoryAxis.visibleAxis =0
    bc.categoryAxis.categoryNames = None
    drawing.add(bc)
