Re: [Gnuplot-info] plotting part of data

[Thomas S. <t.s...@fz...>]

set xrange [0:9]
set yrange [0:10]
# plot all data points
plot 'data1.dat' us 1:2 w lp, 'data2.dat' us 1:2 w lp
# plot only some datapoints
plot 'data1.dat' us 1:($1<=4?$2:0/0) w lp, 'data2.dat' us
1:($1>=2?($1<=7?$2:0/0):0/0) w lp

see 'help ternary'


I have two files:
"data1.dat"       "data2.dat"
    1 2                      1  3
    2 3                      2  5
    4 5                      6  7 
    6 7                      7   5
   7 9                       8   8

So, how plot "data1.dat" from x[1:4] and "data2.dat" from x[2:7] at the same
plot?     

'Masking'  is when drop out some points during line fitting.
