geom_text,为特定分面添加标注,在df中包含分面列,ggplot可以自动识别 # 1.1 (使用字符型)直接在df中定义xyl,让ggplot自动识别分面变量 geom_text(data=data.frame(x=0,y=0,f="a",l="'1.1a:'*CO[2]"),aes(label=l),parse=T,color="red",hjust=0)+ # 1.2 (使用字符型)为不同分面添加不同标...
The concept behind ggplot2 divides plot into three different fundamental parts:Plot = data + Aesthetics + Geometry. The principal components of every plot can be defined as follow: datais a data frame Aestheticsis used to indicate x and y variables. It can also be used to control thecolor,...

shape maps to the shapes of points. We’ll use a different data set for the line graphs here because the PlantGrowth data set does not work well with a line graph. # A different data set df1 <- data.frame( sex = factor(c("Female","Female","Male","Male")), time = factor(c(...
ggplot(data, aes(x, y))+# Draw ggplot2 plotgeom_line()+geom_point() As shown in Figure 1, we created a line and point plot (i.e. a graph where the lines connect the points) using the ggplot2 package with the previously shown R syntax. ...
For example, if there are two colors, then they will be selected from opposite points on the circle; if there are three colors, they will be 120° apart on the color circle; and so on. The colors used for different numbers of levels are shown here: The default color selection uses ...
ggp+# Draw multiple line segmentsgeom_segment(data=data_lines, aes(x=x, y=y, xend=xend, yend=yend, col=col)) After running the previously shown R syntax the ggplot2 scatterplot shown in Figure 4 has been drawn. As you can see, we have added three lines with different colors and ...
data frame is used predominantly as layers are added, but the aesthetics may vary from one layer to another. The third method initializes a skeletonggplotobject which is fleshed out as layers are added. This method is useful when multiple data frames are used to produce different layers, as ...
