  # 添加散点
  geom_point(size=) + 
  # 添加辅助线段
  geom_segment(aes(x=name,xend=name,y=,yend=mpg))

4.2.1 更改点的大小，形状，颜色和透明度

ggplot(df,aes(name,mpg)) + 
  # 添加散点
  geom_point(size=, color="red", fill=alpha("orange", 0.3), 
             alpha=.7, shape=21, stroke=3) + 
  # 添加辅助线段

  theme_bw() + 
  theme(axis.text.x = element_text(angle =,hjust = 1),
        panel.grid = element_blank())

4.2.2 更改辅助线段的大小，颜色和类型

ggplot(df,aes(name,mpg)) + 
  # 添加散点
  geom_point(aes(size=cyl,color=cyl)) + 
  # 添加辅助线段
  geom_segment(aes(x=name,xend=name,y=,yend=mpg),
               size=, color="blue", linetype="dotdash") +
  theme_classic() + 
  theme(axis.text.x = element_text(angle =,hjust = 1),
        panel.grid = element_blank()) +
  scale_y_continuous(expand = c(,0))
## Warning: Using size for a discrete variable is not advised.

4.2.3 对点进行排序，坐标轴翻转

df <- df[order(df$mpg),]
# 设置因子进行排序
df$name <- factor(df$name,levels = df$name)

ggplot(df,aes(name,mpg)) + 
  # 添加散点
  geom_point(aes(color=cyl),size=) + 
  # 添加辅助线段
  geom_segment(aes(x=name,xend=name,y=,yend=mpg),
               size=, color="gray") +
  theme_minimal() + 
  theme(
    panel.grid.major.y = element_blank(),
    panel.border = element_blank(),
    axis.ticks.y = element_blank()
  ) +
  coord_flip()

4.3 绘制棒棒糖图（使用ggpubr）

4.3.1 使用ggdotchart函数绘制棒棒糖图

ggdotchart(df, x = "name", y = "mpg",
           color = "cyl", # 设置按照cyl填充颜色
           size =, # 设置点的大小
           palette = c("#AFBB", "#E7B800", "#FC4E07"), # 修改颜色画板
           sorting = "ascending", # 设置升序排序                        
           add = "segments", # 添加辅助线段
           add.params = list(color = "lightgray", size =.5), # 设置辅助线段的大小和颜色
           ggtheme = theme_pubr(), # 设置主题
)

4.3.2 自定义一些参数

ggdotchart(df, x = "name", y = "mpg",
           color = "cyl", # 设置按照cyl填充颜色
           size =, # 设置点的大小
           palette = "jco", # 修改颜色画板
           sorting = "descending", # 设置降序排序                        
           add = "segments", # 添加辅助线段
           add.params = list(color = "lightgray", size =.2), # 设置辅助线段的大小和颜色
           rotate = TRUE, # 旋转坐标轴方向
           group = "cyl", # 设置按照cyl进行分组
           label = "mpg", # 按mpg添加label标签
           font.label = list(color = "white", 
                             size =, 
                             vjust =.5), # 设置label标签的字体颜色和大小

## Warning: stat_density_tern: You have not specified a below-detection-limit (bdl) value (Ref. 'bdl' and 'bdl.val' arguments in ?stat_density_tern). Presently you havex value/s below a detection limit of 0.010, which acounts for 2.000% of your data. Density values at fringes may appear abnormally high attributed to the mathematics of the ILR transformation. 
## You can either:
##. Ignore this warning,
##. Set the bdl value appropriately so that fringe values are omitted from the ILR calculation, or
##. Accept the high density values if they exist, and manually set the 'breaks' argument 
##    so that the countours at lower densities are represented appropriately.

6.1.3 堆积型华夫饼图

library(dplyr)
nrows <-
ndeep <-

df <- expand.grid(y =:nrows, x = 1:nrows)

categ_table <- as.data.frame(table(mpg$class) * (nrows*nrows))

categ_table<-arrange(categ_table,desc(vals))
categ_table$vals<-categ_table$vals /unit

6.1.4 waffle 包绘制（一个好用的包，专为华夫饼图做准备的）

#waffle(parts, rows =, keep = TRUE, xlab = NULL, title = NULL, colors = NA, size = 2, flip = FALSE, reverse = FALSE, equal = TRUE, pad = 0, use_glyph = FALSE, glyph_size = 12, legend_pos = "right")
#parts 用于图表的值的命名向量
#rows 块的行数
#keep 保持因子水平（例如，在华夫饼图中获得一致的图例）
library("waffle")
parts <- c(One=, Two=30, Three=20, Four=10)
chart <- waffle(parts, rows=)
print(chart)

7 三维散点图绘制

7.1 简单绘制

library("plotD")
#以Sepal.Length为x轴，Sepal.Width为y轴，Petal.Length为z轴。绘制箱子型box = TRUE;旋转角度为theta =, phi = 20;透视转换强度的值为3d=3;按照2D图绘制正常刻度ticktype = "detailed";散点图的颜色设置bg="#F57446"
pmar <- par(mar = c(.1, 4.1, 4.1, 6.1)) #改版画布版式大小
with(iris, scatterD(x = Sepal.Length, y = Sepal.Width, z = Petal.Length,
  pch =, cex = 1.5,col="black",bg="#F57446",
                   xlab = "Sepal.Length",
                   ylab = "Sepal.Width",
                   zlab = "Petal.Length", 
                   ticktype = "detailed",bty = "f",box = TRUE,
                   theta =, phi = 20, d=3,
                   colkey = FALSE)
)

7.2 加入第四个变量，进行颜色分组

7.2.1 方法一

#可以将变量Petal.Width映射到数据点颜色中。该变量是连续性，如果想将数据按从小到大分成n类，则可以使用dplyr包中的ntile()函数，然后依次设置不同组的颜色bg=colormap[iris$quan]，并根据映射的数值添加图例颜色条（colkey()）。
library(tidyverse)
iris = iris %>% mutate(quan = ntile(Petal.Width,))
colormap <- colorRampPalette(rev(brewer.pal(,'RdYlGn')))(6)#legend颜色配置
pmar <- par(mar = c(.1, 4.1, 4.1, 6.1))
# 绘图
with(iris, scatterD(x = Sepal.Length, y = Sepal.Width, z = Petal.Length,pch = 21, cex = 1.5,col="black",bg=colormap[iris$quan],
     xlab = "Sepal.Length",
     ylab = "Sepal.Width",
     zlab = "Petal.Length", 
     ticktype = "detailed",bty = "f",box = TRUE,
     theta =, phi = 20, d=3,
     colkey = FALSE)
)
colkey (col=colormap,clim=range(iris$quan),clab = "Petal.Width", add=TRUE, length=.4,side = 4)

7.2.2 方法二

#将第四维数据映射到数据点的大小上(cex = rescale(iris$quan, c(., 4)))这里我还“得寸进尺”的将颜色也来反应第四维变量，当然也可以用颜色反应第五维变量。
pmar <- par(mar = c(.1, 4.1, 4.1, 6.1))
with(iris, scatterD(x = Sepal.Length, y = Sepal.Width, z = Petal.Length,pch = 21, 
                     cex = rescale(iris$quan, c(., 4)),col="black",bg=colormap[iris$quan],
                     xlab = "Sepal.Length",
                     ylab = "Sepal.Width",
                     zlab = "Petal.Length", 
                     ticktype = "detailed",bty = "f",box = TRUE,
                     theta =, phi = 15, d=2,
                     colkey = FALSE)
)
breaks =:6
legend("right",title =  "Weight",legend=breaks,pch=,
       pt.cex=rescale(breaks, c(., 4)),y.intersp=1.6,
       pt.bg = colormap[:6],bg="white",bty="n")

7.3 用rgl包的plot3d()进行绘制

library(rgl)
#数据
mycolors <- c('royalblue', 'darkcyan', 'oldlace')
iris$color <- mycolors[ as.numeric(iris$Species) ]
#绘制
plotd( 
  x=iris$`Sepal.Length`, y=iris$`Sepal.Width`, z=iris$`Petal.Length`, 
  col = iris$color, 
  type = 's', 
  radius = .,
  xlab="Sepal Length", ylab="Sepal Width", zlab="Petal Length")
