I created two different plots using ggplot2. Is there a way to overlap these two plots in the same axes? enter image description here and enter image description here

    Welcome to Stack Overflow! Could you make your problem reproducible by sharing a sample of your data so others can help (please do not use `str()`, `head()` or screenshot)? You can use the [`reprex`](https://reprex.tidyverse.org/articles/articles/magic-reprex.html) and [`datapasta`](https://cran.r-project.org/web/packages/datapasta/vignettes/how-to-datapasta.html) packages to assist you with that.

When you first learn to make a ggplot(), you'll start by putting the data and aesthetics in the ggplot() function and then adding the layers using this data and aesthetics, e.g.

ggplot(df1, aes(x1,y1)) +
geom_line() +
geom_point()

However, you can supply the data and aesthetics for each layer if you need to, eg

ggplot() +
geom_line(aes(x1,y1), data= df1) +
geom_point(aes(x1,y1), data= df1)

Which also means, you can use different data and aesthetics in each layer, eg

ggplot() +
geom_line(aes(x1,y1), data= df1) +
geom_line(aes(x2,y2), data= df2)
