3. 散点图（Scatter Plot）—— 适用于相关性分析 📌 适用场景：分析两个变量之间的关系，例如“广告支出 vs 销售额”。# 生成示例数据 set.seed(123)data <- data.frame(Advertising = rnorm(100, mean = 50, sd = 10),Sales = rnorm(100, mean = 200, sd = 50))# 绘制散点图 ggplot(data, ...
# Scatter Plot library(ggplot2) ggplt <- ggplot(Orange,aes(x=circumference,y=age))+ geom_point()+ theme_classic() ggplt # Plotting a single Regression Line ggplt+geom_smooth(method=lm,se=FALSE,fullrange=TRUE) R Copy输出这是一个单一的平滑线,或俗称为回归线。在这里,各点是结合在一起...

注意，plotly库还有一个与ggplot无关的函数plot_ly()，它使用的语法类似于ggplot的qplot():plot_ly(snowfall2000s, x = ~Winter, y = ~Total, type = “bar”)原文：ggplot2 is not only the R language’s most popular data visualization package, it is also an ecosystem. Numerous add-on packages ...

You can add an ellipse to your scatter plot adding the stat_ellipse layer, as shown in the example below. # install.packages("ggplot2") library(ggplot2) ggplot(df, aes(x = x, y = y)) + geom_point() + stat_ellipse() Customization The color, line type and line width of the elli...
