multiple graphs in one plot ggplot

Question

My data

ID	Time	Score	Var1	Var 2	Var 3
1	1	100	1	2	1
1	2	150	1	2	1
2	1	200	2	3	4
2	2	-10	2	3	4
2	3	-70	2	3	4
3	1	100	1	2	2
3	2	200	1	2	2

I want to make a ggplot that combines all the variables together. Y variable is = score. X variable is = Time. and for each categorical variable (i.e., var1, var2) I want to see the effect for each level.

My code for one Graph:

var1_graph=ggplot (DB, aes(Time, Score, group_by = ID))+
facet_wrap(~var1)+
geom_smooth()+
theme_bw()
#####Var2
var2_graph = ggplot (DB, aes(Time,Score, group_by=ID))+
facet_wrap(~var2)+
geom_smooth()+
theme_bw()
################
ggarrange(var1_graph, var2_graph, labels = c("A","B"), 
ncol = 1, nrow = 2).

But this isn't what I want because I want them to be in same plot and not to combine multiple plots.

Can do this using a "Pivot_longer function"?

Thanks!

please post data using the results from dput(DB)

Are you looking for something like this?

pivot_longer is used to collect the vars in one column to enable faceting.

library(tidyverse)

tribble(
  ~ID, ~Time, ~Score, ~Var1, ~Var2, ~Var3,
  1, 1, 100, 1, 2, 1,
  1, 2, 150, 1, 2, 1,
  2, 1, 200, 2, 3, 4,
  2, 2, -10, 2, 3, 4,
  2, 3, -70, 2, 3, 4,
  3, 1, 100, 1, 2, 2,
  3, 2, 200, 1, 2, 2
) |> 
  pivot_longer(starts_with("Var"), names_to = "var", values_to = "level") |> 
  ggplot(aes(Time, Score, group = level)) +
  geom_line() +
  facet_grid(level ~ var)

Each var has 4 levels. so I want the graphs to be divided into 4 graphs for each level of var. all the graph have same x axis which is time, and same y axis which is score
