I have two histograms in one window (using facet) and I would like control over the color of the outline and the fill. I've tried looking up color scales
, aes()
, + color
, + fill
, including color and fill in qplot
, all resulting in expected plots!
My code can be found below. (Note: mussel2 has two columns concentration (a list of numbers) and waterbody (listed or reference). I can provide the data if necessary.
I understand this is an elementary question, so I do appreciate your time.
qplot(data=mussel2,
x = Concentration,
xlim = x_lim,
ylim = y_lim,
xlab = expression(paste("Concentrations of DDE (", mu, "g/g)")),
ylab = "Frequency",
binwidth = 1.5)+
theme(legend.position="none")+
facet_grid(Waterbody~.)
