#2061 — Multiple plots with "-" data

Dear all,

is there a possibility to plot more than one sets of data with the "-"
dummy file method?

With real files file1, file2 you can do

plot "file1" <modifiers>,"file2" <modifiers>

but I cannot see how to do this with

plot "-" <modifiers>
<data>
e

The aim is to have a neat demo file for showing two plots without the
need of external data files.

Thanks a lot in advance!

Ingo

Ah, thanks, these "e"'s were the problem; I thought one would do.

If you specify more than one '-'s in a plot command, gnuplot will ask
you for data until it encounters enough "e"s.

gnuplot> plot '-' lt 2, '-' lt 4
input data ('e' ends) > 1
input data ('e' ends) > 2
input data ('e' ends) > 3
input data ('e' ends) > 4
input data ('e' ends) > 56
input data ('e' ends) > 7
input data ('e' ends) > e  # this concludes the first set of data
input data ('e' ends) > 5
input data ('e' ends) > 6
input data ('e' ends) > 7
input data ('e' ends) > 8
input data ('e' ends) > 5
input data ('e' ends) > 4
input data ('e' ends) > 3
input data ('e' ends) > e # after this it finally plots
gnuplot>

Two '-'s were given in the spec, so it keeps asking until it gets two
'e's.

You can even mix normal files and pseudo-files in the plot
specification:

plot '-' lt 2, 'foo.txt' u lt 6, '-' lt 4
