Sankey Diagram

plot(getSankey(colData(muraro)$cell_type1,  muraro_to_seger$scmap_cluster_labs[,1], plot_height=400))

library(RColorBrewer)
library(scmap)
print(load("-/project/singleCell/mouse/Integration/comp.df.Rdata"))
comp.df$New_cluster <- factor(comp.df$New_cluster, levels = 1:13)
unique(comp.df$New_cluster)

plot(getSankey(comp.df$Old_cluster, comp.df$New_cluster, 
               plot_width=400, plot_height=600, colors=brewer.pal(12,"Set1")))

Marginal plot

library(ggExtra)
#  [density, histogram, boxplot, violin].
ggMarginal(pcag, data=pca_HSCR2, groupColour = T, groupFill=T, size=4, type="boxplot")

Heatmap

• Pheatmap
• ComplexHeatmap Complete Reference

坐标轴

去掉不必要的到坐标轴的距离，使图形更加紧凑

ggplot2 Bar Graph remove unnecessary distance between axis label and 0 count on y axis

scale_y_discrete(expand = c(0,0))　　

在对应的坐标轴里用expand来控制

坐标轴以百分比显示

scale_y_continuous(labels = percent_format()）

x和y轴对角线翻转

coord_flip()

　　

图例

图例的顺序翻转

scale_fill_manual(guide = guide_legend(reverse=F))

　　

分面

添加直线

geom_hline(yintercept=0, linetype="dashed", color = "gray30", size=0.1) +
geom_vline(xintercept=6, color = "gray30", size=0.1) +
