问题描述

By default, ggplot2 produces plots with a grey background. How do I change the color of the background of the plot?

例如，由以下代码生成的图:

For example, a plot produced by the following code:

library(ggplot2)
myplot<-ggplot(data=data.frame(a=c(1,2,3), b=c(2,3,4)), aes(x=a, y=b)) + geom_line()
myplot

推荐答案

要更改面板的背景颜色，请使用以下代码:

To change the panel's background color, use the following code:

myplot + theme(panel.background = element_rect(fill = 'green', colour = 'red'))

要更改绘图的颜色(但不是面板的颜色)，您可以:

To change the color of the plot (but not the color of the panel), you can do:

myplot + theme(plot.background = element_rect(fill = 'green', colour = 'red'))
