Hello Firas,

you can use package "ggplot2" in R for displaying time seres data. In this case you should create a data.frame with 4 columns:

- date (type date; you will use this with scale_x_date() and mapping = aes(x = date))

- time scale (type numeric or integer; mapping = aes(y = time_scale))

- value (type numeric; containing SSI/SSP values; mapping = aes(colour = value))

- subplot (type categorical of four levels for the four subplots; the order of the level is important!; facet_grid(rows = vars(subplot)))

HTH,

Ákos

did you find the answer?

In R, your best shot is probably https://stackoverflow.com/questions/27135962/how-to-fill-with-different-colors-between-two-lines-originally-fill-geom-poly. In addition, matplotlib in python can do a better job, see for example https://stackoverflow.com/questions/36954416/colour-fill-based-on-values.
