Selecting series in a chart based on a range and manual inputs
 

Hello,

I am plotting a chart of 12 numbers on the Y axis.
8 of the numbers are in a range a1:a8.
Remaining 4 numbers are manual.

Hence I would need to select the values in the series for thechart as
something like:
(a1:a8,num1,num2,num3,num4)
However I am not getting this syntax correct.

Any ideas how I can write this in the correct syntax?

Thank you!
