Re: [Gnuplot-info] plot dstat output cvs file

Hi Bart,

I read again the description of 'every' carefully (which I also 
recommend to you ;-).
Obviously, empty lines in data rows seperate individual data blocks.
So, if there is an empty line in your data it starts a new block.

Let's use the simplified data:

"blabla1",,,
"blabla2",,,
"blabla3",,,
"blabla4",,,

"blabla6",,,
"date time","A","B","C"
30-10 11:19:40,1.0,2.0,3.0
30-10 11:19:41,1.1,2.1,3.1
30-10 11:19:42,1.2,2.2,3.2
30-10 11:19:43,1.3,2.3,3.3
30-10 11:19:44,1.4,2.4,3.4

The command to plot this:

plot 'Data.dat' u 1:2 every 1:1:2:1 w lp t "Title 2"    # and so on...
    which is equivalent to
plot 'Data.dat' u 1:2 every ::2:1 w lp t "Title 2"

# explanation of every 1:1:2:1
data points increment is 1
block increment is 1
starting point is 2 (points in each block start from 0)
starting block is 1 (blocks start from 0)

However, I have not found a way to automatically take the columnheaders 
from line 2 of block 1.
gnuplot seems to always take line 0 from block 0.
