Example: Drawing ggplot2 Plot with Lines & Points The following syntax illustrates how to create a ggplot2 scatterplot with lines. First, we need to install and load theggplot2 package: install.packages("ggplot2")# Install & load ggplot2 packagelibrary("ggplot2") ...
Scatter plot with linear regression line of best fit 图1,显示不同类别 df <- ggplot2::mpg %>% setDT() df_select <- df[cyl %in% c(4,8),] %>% .[,cyl:=as.factor(cyl)] cyl_color <- c("#1f77b4", "#ff983e") # geom_smooth的填充范围,只有数据和全图可选,而且se只会按垂直方向...

第一选择一定是散点图(Whenever you want to understand the nature of relationship between two variables, invariably the first choice is the scatterplot);ggplot2中用来画散点图的函数是geom_point(),同时可以用geom_smooth()函数添加拟合
1.2 带边界的散点图(Scatterplot With Encircling) 在介绍结果时,有时我会在图表中加上某些特殊的点或区域组,以便引起人们对那些特殊情况的注意。使用ggalt包中的geom_encircle()可以方便地完成此操作。在geom_encircle()中,将数据设置为仅包含点(行)或兴趣点的新数据帧。此外,还可以展开曲线,以便仅在点之外通过...
title="Scatterplot with overlapping points", caption="Source: midwest") 上图中其实有很多点是重合的 原始数据是整数 1 dim(mpg) 用jitter_geom()画抖动图 重合的点在原先的位置基于一定阈值范围(width)随机抖动 1 2 3 4 5 6 7 8 9 10 11 12 library(ggplot2) data(mpg, package="ggplot2")...
