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") ...
# 确保图形显示 print(ggplot(data, aes(x = x, y = y, color = group)) + geom_point() + labs(title = "Scatterplot Example", x = "X Axis", y = "Y Axis") + theme_minimal()) 确保所有需要的包已经正确加载,特别是 ggplot2 包。 代码语言:txt 复制 # 加载 ggplot2 包 library(ggpl...
Example 1: Draw ggplot2 Scatterplot Using theme_bw()ggplot(data, # theme_bw scatterplot aes(x = x, y = y, col = group)) + geom_point() + theme_bw()Example 2: Draw ggplot2 Density Plot Using theme_bw()ggplot(data, # theme_bw density plot aes(x = x, fill = group)) + ...
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...
library(scatterplot3d) data(trees) scatterplot3d(trees, type = "h", highlight.3d = TRUE, angle = 55, pch = 16) 上面函数 scatterplot3d( )中的参数 type 用于设置绘图的类型,默认为“p”(点),这里设为“h”,显示垂线段。参数 angle 用于设置 x 轴和 y 轴的角度。需要注意的是,用静态的三...
library(ggplot2) # 创建数据集 data <- data.frame( x = 1:10, y = rnorm(10) ) # 绘制散点图并添加水平线 ggplot(data, aes(x = x, y = y)) + geom_point() + geom_hline(yintercept = 0, linetype = "dashed", color = "red") + labs(title = "Scatter Plot with Horizontal Lin...
A plot may have multiple layers, as in the example where we overlaid a smoothed line on a scatterplot. All together, the layered grammar defines a plot as the combination of: • A default dataset and set of mappings from variables to aesthetics. • One or more layers, each composed ...
gg <- ggplot(diamonds, aes(x=carat, y=price, color=cut)) + geom_point() + labs(title="Scatterplot", x="Carat", y="Price") # 增加坐标轴和图像标题 print(gg)#保存图形 1. 2. 3. 4 主题和格式调整 使用Theme函数控制标签的尺寸、颜色等,在element_text()函数内自定义具体的格式,想要清除...
# Scatter plot: clarity (x), carat (y), price (color)ggplot(diamonds, aes(x = clarity, y = carat, color = price)) + geom_point(alpha =0.5)# Dot plot with jitteringggplot(diamonds, aes(x = clarity, y = carat, color = price)) + ...
This post provides reproducible code and explanation for the most basic scatterplot you can build with R and ggplot2.
