You never did provide a reproducible example or say how you wanted to
plot. Here is a way to get a subset of t1 or t2, and you can then use it
as input to ggplot:
your_subset <- df %>%
mutate(key = grep(".*(t1|t2).*", "\\1", Command, value = TRUE))
filter(!(Command %in% c('t1', 't2')))
This will give you a subset with just t1/t2 and you can use 'key' as the
colour option for ggplot.

What is the problem that you are trying to solve?
Tell me what you want to do, not how you want to do it.
