I have a data file organized as the following d channel ... k = 1 0.34 0.89 0.99 0.23 0.67 0.02 0.65 0.99 0.45 k=2 0.45 0.78 0.99 0.23 0.78 0.86 0.12 0.43 0.23 ... m channel ... k=1 ... I need to skip the first 3 lines then splot the first set of data forming 3 by 3 matrix, and then skip a line, splot the second set of data forming 3 by 3 matrix again ... How can I do that? If I use splot 'file' ev 4:6 matrix , then it complains that Matrix does not represent a grid, Can anybody explain where the above command goes wrong? Thank you very much!! |

turn all non-data lines into comments by adding a '#' in front
and plot with
splot 'file' matrix ind 0 w l, '' matrix ind 1 w l, ...
otherwise, you need gnuplot 4.3-cvs.
the first plot goes into a table:
set table
set out 'table'
splot 'file' every 2:1:1:1:3:1, '' every 2:1:5:1:8:1, ...
set out
see 'help every', the 1st block ('d channel') in your
data file is empty, the 2nd contains the data from 'k=1'
to 'k=whatever', the 3rd ('m channel') is empty, the
4th contains data, that's why we take every 2nd
block.
inside one block data lines are selected from 1 to 3,
5 to 8, a.s.o.
and this table is then read in again:
set xrange [0:2]
splot 'table' matrix ind 0, '' matrix ind 1, ...
the warnings are due to the 'i' at the end of each data line
in 'table'.

Thanks all for your great help, the modification into comments is trivial
and I will do that!
So actually the problem boils down to how gnuplot see a data file. In my
naive imagination, it recognizes line separators(if there exists this in
linux), and thus it could count how many lines it is instructed to read in
and how the readin data should be organized and displayed. Following this
logic, it seems to me not a big problem to splot continuously the data file
I presented. But it does not work out as I expected, can anybody clarify
this for me?

if you would do a normal 'splot', selection of data section using 'every'
would work, but with 'matrix' gnuplot tries to figure out what the
dimensions
of the matrix are, and there it fails due to those non-data lines (e.g. 'k =
1').
