Removing a part of a graph

Hi @MarieFr , could you try put a reproducible example of data?

see this:

--

# An easy way is paste the result of:

dput(head(yourdataframe, 30))

One way around that might be to set the dates as a factor type and then filter out values other than 0. But first you must arrange the dates so that they are in order on the x-axis.
