Bar plots are automatically stacked when multiple bars are at the same location. The order of the fill is designed to match the legend. library(plotly) g <- ggplot(mpg, aes(class)) p <- g + geom_bar(aes(fill = drv)) ggplotly(p) Showing mean library(plotly) df <- data.frame(...
今天我们介绍一下Bar Plots 主要函数及参数 • Key function: geom_bar()• Key arguments to customize the plot: alpha, color, fill, linetype and size.数据类型 library(ggplot2)df <- data.frame(dose=c("D0.5", "D1", "D2"), len=c(4.2, 10, 29.5))head(df)df2 <- data.fra...
Bar plots in ggplot2 with the geom_bar and geom_col functions. Flip the axes, add labels to the bars, reorder the bars and customize the colors and the legend
1. 对数值进行排序 require(plyr)# Sort by dose and suppdf_sorted <- arrange(df2, dose, supp)head(df_sorted)2. 分别计算Y轴数值的和 df_cumsum <- ddply(df_sorted, "dose", transform, label_ypos=cumsum(len))head(df_cumsum)3. 画图 ggplot(data=df_cumsum, aes(x = dose, y = len...

p <-ggplot(mydata, aes(months, values)) p +geom_bar(stat = "identity", aes(fill = type)) Cool! Sort of. We have stacked bar plots, but I want them next to one another, not stacked. We can fix that with one more change to our code using dodge. p <-ggplot(mydata, aes(mo...
