You want something like this:
239,13
239,21 478,34
239,3 717,64
239,38 957,02
239,46 1196,48
239,55 1436,03
0,35 0,35
0,44 0,79
0,53 1,32
0,6 1,92
0,68 2,6
0,78 3,38
0,85 4,23
0,93 5,16
If the values are accumulated sums, it seems funny to sum them again.
Since I don't want to solve the wrong problem, I suggest that you post
o The CREATE TABLE statement for your table (possibly simplified).
o INSERT statements with sample data.
o The desired output given the sample.
That is likely to give you a tested solution. Whereas from what you
have posted now, at best could give you guesses.
