Hello, i'm using Rstudio from a few day, and i have some information in a CVS file, take every five second, format of the time is HH:MM:SS. I use the hour on the X axis, but i don't want having all the time print. For example only every 10 values. I think it will be possible with scale_x_datetime(breaks = date_breaks(XXX) but i don't understand how select every 20 s. Thank's for your help Fran?ois-marie BILLARD -- Informatique <informatique at billard-francois-marie.eu>
