R-users it appears I am leaning on your knowledge once again. Is there any way to add a
vertical line to a histogram and qplot "stacked" plot? Here is my current
attempt:
"qplot" approach attempt:
qplot(Run, data = data_dataframe, breaks = breaks, fill = Temperature, main = short_title) + scale_x_continuous("Data") + scale_y_continuous("Freq") + scale_fill_discrete("Temperature") + scale_fill_manual(values = c(LOW = "blue", AMB ="black", HIGH = "red")) + geom_abline(v = HighVal, col = "dodgerblue3", lty="dotdash")
"hist" approach attempt:
hist(data_dataframe, breaks = breaks, col = "dodgerblue3", xlab="Data", freq = TRUE, main="") +abline(v = HighVal, col = "dodgerblue3", lty="dotdash")
Are you using ggplot2? It uses that notation of adding elements to a
plot. Classic graphics doesn't, so you would just give the different
commands separately on each line, e.g.
hist(data_dataframe, breaks = breaks, col = "dodgerblue3", xlab="Data",
freq = TRUE, main="")
abline(v = HighVal, col = "dodgerblue3", lty="dotdash")
