Dear Robin,

My excusses for not providing you with a runnable example.
I try to be clearer.

##############################

Before adding 'data3' the output look like in the first image below. The
data point values with red arrows are on or below the line, when
'data3'  is added
(second image below) these marked values can no longer be seen.  When I
increase the 'lineLabelNudge', the values only move further from the line,
or when I make it really small (e.g. 0.5), all the values move to on the
line but are only half visible.
Since in all the examples that I could find the values are shown above the
lines, I wondered whether there is setting that I have missed ?
Hope this was clearer,
Regards,
Helga
