Plotting datapoints of different blocks in one graph

Show all headers | View raw

Hi everybody,

I have a dataset, consitsting of multiple blocks. I used that to get different plots for each block. Now I need only the nth line of each block and I need gnuplot to plot this as one graph.

Illustration:
# Datablock 1
1  2.3
2  2.4   <-- 1st datapoint I need
3  2.5

# Datablock 2
1  3.3
2  3.4   <-- 2nd datapoint I need
3  3.5

#...
.
.       <-- ...
.


I can plot these points separately, making use of "every ::2::2" (and leaving out "index" at all), but gnuplot doesn't combine them to a dataset (for example: "with linespoints" gives me still single dots). That would be crucial, because I need a fit through these points.

Any ideas would be greatly appreciated!
Thanks,
Georg
