data cutoff threshold for `plot`

Show all headers | View raw

[ gnuplot 4.6 ]
Is there something like a threshold that applies to a single plot type after `plot` is given? If this can be done using two y-axes, there's already a lot in the newsgroup for that I can try.

I have some x/y data. I'd like to combine impulses with a line, however, I'd like to plot the line for data below some threshold. e.g. impulses for all data, but a line to connect tops of the impulses for data points below some value e.g. 5000 (see below)

imaginary pseudo-code to illustrate what I'd like to do:

yrange [0:10000]
plot \
'data.dat' u 1:2 w i, \
''         u 1:2 w l threshold=5000

... so the plot will have impulses above 5000 that stand alone and are not connected to those below 5000. the ones below will appear connected.
