ggplot2 中去除边框线和背景色的一些操作library(ggplot2)#p1 - ggplot(diamonds, aes(x = color)p2 - p1 + layer( geom = bar, geom_params = list(fill = blue, colour = yellow), stat = bin, stat_params = list(binwidth = 2) )# 去除背景色p_remove_bg - p2 + theme_bw()p_remove_bg# 去除网格线p_remove_grid - p2 + theme(panel.grid.major = element_blank(), panel.grid.minor = element_blank()p_remove_grid# remove border linesp_remove_border - p2 + theme(panel.border = element_blank()p_remove_border# 去除背景色和 边框p_remove_two - p2 + theme(panel.background = element_blank()p_remove_two# add axis line 添加坐标轴p_axis - p2 + theme(axis.line = element_line(colour = black)p_axis# 合并的操作 1p_all_1 - p2 + theme(panel.grid.major = element_blank(), panel.grid.minor = element_blank(), panel.background = element_blank(), axis.line = element_line(colour = black)p_all_1# 合并的操作 2p_all_2 - p2 + theme_bw() + theme(panel.border = element_blank(), panel.grid.major = element_blank(), panel.grid.minor = element_blank(), axis.line = element_line(colour = black)p_all_2效果上来看，肯定是最后一幅图是最好的效果的，大家自己操作一下。
