Re: [R] Help with plotting and date-times for climate data

Change geom_point(aes(y = tmax_mean, color = "blue")) to geom_point(aes(y = tmax_mean), color = "blue") if you want blue points. aes(color = ) does not set the color of the points. aes(color = ) takes a column (best if it is a factor) and uses that for different colors. /Martin On Tue, Sep
