plot - Plotting CSV with semi-colons and time formatted data with Gnuplot -

i have 2 csv files on 80k strings in each.

the first file have structure:

12.11.12 - 00:59:58;428,8; 12.11.12 - 00:59:59;428,9; ... 12.11.12 - 21:53:32;592,7; 12.11.12 - 21:53:35;596,4; ... 14.11.12 - 12:31:41;510,0; 14.11.12 - 12:31:41;510,0; 

and second have scructure:

1;428.9; 1;428.9; 5;428.9; ... 117109;673.6; 117110;672.8; 117111;672.8; ... 214241;497.2; 214241;497.2; 214258;507.3; 

how can plot both of csv files in gnuplot?

p.s. first column must x , second must y.

first, apparently can set delimiter thus:

set datafile separator ";" 

then set time format first file, , set x time axis:

set timefmt "%d.%m.%y - %h:%m:%s" set xdata time 

plot first file

plot "data1.csv" using 1:2 

the second file x values don't seem have date format, instead perhaps seconds elapsed? that,

set datafile separator ";" plot "data2.csv" using 1:2 

and don't set xdata time. should have x axis in seconds. if need plot both @ same time, simplest pre-process 1 other.
