ggplot2是基于grid的绘图工具,它绘制的图像其实是由多个grob(grid graph object)组成的,比如一张点图,它的标题是titleGrob,点图的基本单元包括pointsGrob。...很多工具包都可以进行拼图或嵌图, 比如cowplot、patchwork、ggpubr、gridExtra等等,但是gtable是相对底层的进行操纵ggplot2对象的包。...还可以定义多行或者...
Plot with multiple lines Well plot both ‘psavert’ and ‘uempmed’ on the same line chart. Solution 1: Make two calls to geom_line(): ggplot(economics, aes(x=date)) + geom_line(aes(y = psavert), color = "darkred") + geom_line(aes(y = uempmed), color="steelblue", line...

It’s as painless as storing it in a variable using the ggpacket() function.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(g...
Lines (ggplot2)) - Add lines to a graph. Facets (ggplot2)) - Slice up data and graph the subsets together in a grid. Multiple graphs on one page (ggplot2)) Colors (ggplot2)) 学了那么多语法,就在菜谱里面把握细节吧! 最后一个是https://stackoverflow.com/ ...
R语言ggplot2可视化、在一张图中画出两条曲线(two lines in same ggplot2 graph)、使用postscript函数将可视化图像保存到指定目录的(ps、postscript file)文件中 #create data frame df <- data.frame(day = c(1, 2, 3, 4, 5, 6, 7, 8, 9, 10), sales = c(8, 8, 7, 6, 7, 8, 9...
But then with multiple subjects in one graph in stead of markers. Now I’m looking for an easy way to create the same plot, but then for marker A, B, C etc. It would save me a lot of time if I don’t have to copy paste a few lines of code and edit the Marker value. Hope...
splitTextGrob() [in the package RGraphics] : for adding a text to a graph Make sure that the package RGraphics is installed. library(RGraphics) library(gridExtra) # Table p1 <- tableGrob(head(ToothGrowth)) # Text text <- "ToothGrowth data describes the effect of Vitamin C on tooth grow...
