R: ggplot background gradient coloring
Solution 1: [1]
you can print/draw the plot on top of a rasterGrob,
library(ggplot2)
library(grid)
library(ggthemes)
reds <- c("#7B0664", "#E32219")
g <- rasterGrob(reds, width = unit(1, "npc"), height = unit(1, "npc"), interpolate = TRUE)
p <- ggplot(data = economics, aes(x = date, y = unemploy)) +
geom_line( alpha=1, color = "white", size = 0.5 ) +
xlab("Years") + ylab("Unemployed [thousands]") +
theme_base() +
theme(panel.background=element_blank(),
panel.border = element_blank(),
plot.background=element_blank(),
text = element_text(colour="white"),
line = element_line(colour="white")) +
theme()
grid.newpage()
grid.draw(g)
print(p, newpage = FALSE)
