The example code below creates a bar chart from Boston snowfall data, and it has several lines of customizations that I’d like to use again with other data. The first code block is the initial graph: library(ggplot2) library(scales) library(rio) snowfall2000s <-import(“https://gist.gi...

Order of the bars of the bar graph The default order of the bars depend on the levels of the factor variable. In our example you can check the order of the bars withlevels(as.factor(df$group)). However, you reorder the bars in several ways: changing the limits withscale_x_discrete,...
利用ggplot2包中的geom_bar()绘制柱状图: df3a %>% ggplot(aes(as.factor(site), Mean, fill=as.factor(site)))+ geom_bar(stat = "identity", width = 0.75)+ geom_errorbar(aes(ymin=Mean-se, ymax=Mean+se), width=0.15)+ scale_fill_manual(values = c('#BBB8DF', '#F8B65C', '#80B...

我的私人库:https://github.com/leezx/FigureCode The R Graph Gallery- R绘图代码库、案例大全 themes -https://www.r-graph-gallery.com/ggplot2-package.html#themes 要开始修饰以前的核心图片,准备发表论文了。 把之前比较raw的图修饰格式,统一生成高清晰图片,准备放入paper中。
ggp1<-ggplot(data)+# Draw ggplot2 barplotgeom_bar(aes(group, sample), stat="identity")ggp1 By executing the previous code we have plotted Figure 1, i.e. a ggplot2 bargraph without any lines or secondary y-axes. Let’s modify this plot!
