Hola Sergio,
The others are right – it would help to have a reprex. Regardless, it seems you have a few different problems:
- Dates are in different formats
- Merging the datasets
- Plotting different 'facets' of the data.
Here are some resources to solve each:
- lubridate package, for working with dates: https://lubridate.tidyverse.org/
- joins in dplyr, to merge your data: Mutating joins — mutate-joins • dplyr
- facet wrapping in ggplot2: 17 Faceting | ggplot2
Best,
Tom
