Hi R users,
I was trying to plot a graph with a secondary axis, and used the following
code for the data but the secondary line and secondary y -axis value did
not match. I would like to show both lines in one graph.
Any suggestions?
library(ggplot2)
library(reshape2)
daT<-structure(list(x = c(1L, 2L, 3L, 4L, 5L, 6L, 7L, 8L, 1L, 2L,
3L, 4L, 5L, 6L, 7L, 8L), y1 = c(9754L, 1051L, 5833L, 5769L, 2479L,
470L, 5828L, 174L, 2045L, 6099L, 8780L, 8732L, 4053L, 9419L,
4728L, 3587L), y2 = c(0.51, 0.61, 0.3, 0.81, 0.89, 0, 1.9, 0.76,
0.87, 0.29, 0, 0.42, 0.73, 0.96, 0.62, 0.06), group = c("A",
"A", "A", "A", "A", "A", "A", "A", "B", "B", "B", "B", "B", "B",
"B", "B")), class = "data.frame", row.names = c(NA, -16L))
print(daT)
daT1<-melt(daT, id.vars=c("x", "group"))
daT1%>%
ggplot() +
geom_line(aes(x = x, y = value, group = variable, color = variable)) +
facet_wrap(~group) +
scale_y_continuous(sec.axis = sec_axis(~ .*0.0001))
