set style increment user

[Allin C. <cot...@wf...>]

The above-noted "set" option is one that is gone in 5.0. I'm not sure what 
is the recommended replacement. I'm thinking of this sort of thing in 
gnuplot 4:

set style line 1 <whatever>
set style line 2 <whatever>
set style line 3 <whatever>
set style increment user
plot <data1> w l, <data2> w l, <data3> w l

and the 3 lines would come out in the respective 3 user-defined styles. 
Now admittedly the "increment user" thing seemed a bit odd; you might
expect the user-defined line-styles to apply automatically. However, it 
did the job. Now that it's gone, is there a compact alternative way of 
telling gnuplot to use user-defined styles in sequence?

If I simply comment out the "increment user" line above in gnuplot 5.0, 
the user-styles are ignored in favor of the default ones. I can get them 
to be used by doing

plot <data1> ls 1 w l, <data2> ls 2 w l, <data3> ls 3 w l

But this is "more work," and creates more opportunity for error, than 
arranging just once for the styles to be used sequentially.
