xtics newline don't work

[benschneider]

yeah I think python interprets those special characters, so you need to escape the escape characters :).
try : "\\n" instead of "\n"

thanks .. but still no luck
using \n it prints → 06.12.\n12

using one single \n it result an error.

full command: gp.c("set xtics format '%d.%m\n%HUhr' textcolor 'black'")
one more idea?

[benschneider]

does this one work: gp.c(r"set xtics format '%d.%m\n%HUhr' textcolor 'black'")
?

[dreamonhigh]

still no luck :(
it through no error. but still no linefeed at this point.

[dreamonhigh]

It prints "06.12\n12" as label, no linefeed but \n is printed instead

[dreamonhigh]

no more idea?

For the meantime, you could once type them in in gnuplot then use : save 'myfile.gn'.
open "myfile.gn" edit / shorten it to your needs and load that one when needed.

can you please tell me the full command string that you are trying to generate and pass from python to gnuplot?
i.e. example code ?

[benschneider]

It might be good to "prepare" the '%d.%m\n%h' string beforehand, i.e. store it in a separate variable, so you can check if python is parsing it right.

sorry. tried a lot of things without luck. here is a easy example.
linefeed is ignored or \n is printed but not done.
example makes no sense, but I'm only interested in \n to linefeed.

import PyGnuplot as gp
gp.c("set title 'XXXXXXXXXXXXXXXXXXXXXXX")
gp.c(r"set xtics format 'Line1\nLine2' textcolor 'black'")
gp.c("plot [-10:10] sin(x),atan(x),cos(atan(x))")

[benschneider]

Just running this directly in gnuplot gives me the exact same results as run via PyGnuplot.

So I tried changing the command itself until I got a new line working:

set xtics format "Line1\nLine2" textcolor "black"

turns out gnuplot requires " marks not ' marks ;).

so your command needs to be:

gp.c("set title 'XXXXXXXXXXXXXXXXXXXXXXX'")
gp.c(r'set xtics format "Line1\nLine2" textcolor "black"')
gp.c("plot [-10:10] sin(x),atan(x),cos(atan(x))")

hello Ben.
Yes this works fine.
Thank you very much!
