Let’s modify this plot! Example 1: Add Line to ggplot2 Barplot Example 1 illustrates how to overlay a line on top of a ggplot2 barchart. To achieve this, we can apply the geom_line function as shown below. Note that we are multiplying the variable that we want to overlay as a lin...
Add labels to a dodged barplot : ggplot(data=df2, aes(x=dose, y=len, fill=supp)) + geom_bar(stat="identity", position=position_dodge())+ geom_text(aes(label=len), vjust=1.6, color="white", position = position_dodge(0.9), size=3.5)+ scale_fill_brewer(palette="Paired")+ t...
#将dose转换weight因子ToothGrowth$dose<-as.factor(ToothGrowth$dose)# 检查数据head(ToothGrowth)library(ggplot2)p<-ggplot(ToothGrowth,aes(x=dose,y=len))+geom_boxplot()p image.png 1.2 更改主标题及轴标题 1.2.1 使用 ggtitle(), xlab() and ylab() p + ggtitle("Plot of length \n by dose") ...
theme(plot.title = element_text(family = "Bangers", hjust = .5, size = 25), plot.subtitle = element_text(family = "Playfair", hjust = .5, size = 15)) 更改多行文本的间距 可以使用lineheight参数来更改行与行之间的间距。在这个例子中,我把线条压在一起(lineheight < 1)。 ggplot(chic, ...
线(line,vline,abline,hline,stat_function等):一般是基于函数来处理位置 射(segment):特征是指定位置有xend和yend,表示射线方向 面(tile, rect):这类一般有xmax,xmin,ymax,ymin指定位置 棒(boxplot,bin,bar,histogram):往往是二维或一维变量,具有width属性 ...
## 饼图(柱状图+极坐标) ggplot(dat, aes(x="", y = num, fill = city)) + geom_bar(width = 1,stat = "identity") + coord_polar(theta = "y") + geom_text(aes(y = pos, label = paste(round(num / sum(num) * 100, 2), "%", ""))) + scale_fill_manual(values = rainbow...

函数ggplot()可以设置图形,但是没有视觉输出,需要使用一个或多个几何函数向图形中添加几何对象(geometric,简写为geom),包括点(point)、线(line)、条(bar)等,而添加几何图形的格式十分简单,通过符号“+”把几何图形添加到plot中 ggplot()+geom_xxx()
