Setting dates on x-axis with ggplot2

Question

I've gone through all similar questions, but still I struggle to find a solution to my problem.

I have this code:

finl <- as.data.frame(cbind(plus,centre,minus,indx))
head(finl)

> head(finl)
     plus    centre     minus indx
1 0.5202951 0.3699147 0.2195342    1
2 0.5328857 0.3890009 0.2451162    2
3 0.5421306 0.3979195 0.2537085    3
4 0.6421294 0.5154826 0.3888357    4
5 0.7312431 0.6132432 0.4952434    5
6 0.7325199 0.6089201 0.4853203    6


ggplot(finl) +
geom_line(aes(indx,centre), group = 1) +
geom_ribbon(aes(x = indx, ymax = plus , ymin = minus), alpha = 0.6, fill = "skyblue") +
ggtitle("Movement over time")+
theme(plot.title = element_text(size=20, face = "bold")) +
theme(plot.title = element_text(hjust = 0.5)) +
theme(axis.text.x=element_blank(),
    axis.ticks.x=element_blank(), 
    axis.title = element_text(size=14))+
labs(x="Period", y="Y-value")

And here is the graph - Plot

Also I have variable date:

date <- ldate[-c(length(ldate))]
date <- as.Date(date)
head(date)

> head(date)
[1] "2008-11-28" "2008-12-31" "2009-01-30" "2009-02-27" "2009-03-31" "2009-04-30"

My question is how to put these dates as an x-axis on my graph?

I've tried with scale_x_date, but somehow I am not able to solve this problem and to get appropriate graph. I get some strange results.

Thank you in advance.

Thanks! But now only four years are on the axis. Do you know how to put all years (from 2008 to 2016) on the axis instead only some of them? — Luka

if you only want years: date <- seq(2008, 2016) but maybe you want to use a time series library. — alfonso.kim

First insert the dates into the dataframe:

finl<-cbind(finl,date)

Then replace indx with the date column of finl in your ggplot code
