I know it is possible because I’ve made it a long time ago, but I can’t remember - how
and the code is deleted. 
But how can I supress the annotation in the right subplot?
using Plots
data=rand(50)
leer=zeros(50)
plot([leer data], layout=(1,2), leg=:false, grid=:off, ann=(5,0,text("Sample text")))
Many thanks for tips.
plot(
plot(
...;
annotation
),
plot(
...
);

Choose a descriptive title that captures the key specific part of your question, eg “plots with multiple axes” instead of something generic like “help me with plotting” . Make use of tags and categories; you can edit those and the title after posting , too. These will make it more likely that your question will be seen by the people who can potentially help.
@trilobit, with annotate!() one can direct the annotations to each subplot.
Example for a 2x2 layout:
using Plots
data = rand(4, 50)
p = plot(data, layout=(2,2), leg=:false, grid=:off, ylims=(0,1.2))
annotate!(p[1], 2.5, 1.1, text("subplot-1"))
annotate!(p[4], 2.5, 1.1, text("subplot-4"))
