In each empty cell enter =NA(); this will display as #N/A.
The line on chart will be continuous.
OR
Click chart; use Tools|Options; open Chart tab and look at "Plot empty cells
as"
best wishes

I have the following as an example set of data points to be plotted on
either
a line or scatter chart (doesn't matter which as I am having the same
problem
with both!)

X Y1 Y2
1 2 1.8
2 4
3 6 4.5
4 8
5 10 9
6 12

I get a line drawn between the points for Y1, but because there is not a
Y2
value for every point on the X-axis then I just get points and no line,
despite a line being selected for in the options! Does anyone know how to
get
this line added on?

Thanks
