我试图通过将 x 轴分成嵌套的样本子类别来改进该图的可视化。我无法使用 ggplot fill 来完成此操作,因为我已经使用了ivot_longer() 来包含 6 种类型的输出。该解决方案还必须允许使用facet_wrap()进行自由缩放视图,以检查各个蛋白质成分之间的趋势。

>2 CTRL_D02 CTRL CC 2 Protein2 0.000000000

>CC <- data %>% slice(1:144)
>LG <- data %>% slice(145:210)
ggplot,堆叠条形图,用于查看所有蛋白质的广泛数量
p0 <- ggplot(CC) +
geom_col(aes(x = ShortName, y = Conc, fill = Group)) +
theme_clean() +
theme(axis.text.x = element_text(angle = 90, vjust = 0.5, hjust = 1)) +
labs(y = "Concentration", x = "Sample", fill = "Composition")
ggplot,查看单个蛋白质成分的趋势
p0.1 <- p0 +
facet_wrap(. ~ Group, scales = "free_y") +
theme(legend.position="none")
您可以使用 ggh4x 包来嵌套 x 轴刻度标签。
library(ggplot2); library(ggh4x)
ggplot(CC, aes(x=interaction(Day,Mod), Conc, fill = Group)) +
geom_col() +
scale_x_discrete(guide="axis_nested") + # *** ggh4x *** #
facet_grid(~Mod, scales = 'free') +
labs(x="Sample", y="Concentration", fill="Composition",
title="Stacked bar graph of convoluted timecourse") +
#theme_clean() +
theme_minimal() +
theme(axis.text.x = element_text(angle = 90, vjust = 0.5, hjust=1),
panel.grid.major.x = element_blank(),
panel.grid.minor.x = element_blank(),
strip.text = element_blank(),
axis.line.x = element_line(),
axis.line.y = element_line(),
legend.box.background = element_rect())
数据:
data <- tibble(Day=sample(c('D02','D04','D07','D11','D02','D14'), 210, TRUE),
