I have a CSV file like:
date;foo
2016-07-01;0,54
2016-08-01;0,54
2016-09-01;0,50
2016-10-01;0,49
but then read into R and plotted
foo2 <- read.csv2("here")
ggplot(foo2, aes(x=date, y=foo))
The output is empty. Ie axes are present but no points are plotted. A regular plot(foo2$foo)
simply plots the points - what could be wrong here?
You need to add a geom to your plot. If you want a line plot add...
ggplot(foo2, aes(x=date, y=foo)) + geom_line()
If you want a scatter plot...
ggplot(foo2, aes(x=date, y=foo)) + geom_point()
You can find more geoms here .
