Add labels to a dodged barplot: p + geom_text( aes(label = len, group = supp), position = position_dodge(0.8), vjust = -0.3, size =3.5) Add labels to a stacked bar plots. 4 steps required to compute the position of text labels: ...
ggplot(data = df, mapping = aes(x = times, y = value)) + geom_line() 善于发现的你,可能会注意到上面三段代码有一个重要的不同之处,那就是第一段和第二段代码中含有‘group = 1’的设置。这样做是因为横坐标的属性设置为了因子,即将连续型的年份和离散型的字符转换为因子,如果不添加‘group = 1...

barplot()第一个向量用来设定条形的高度,第二个向量用来设定每个条形对应的标签(可选)。 变量值条形图: 两个输入变量,x为分类变量,y表示变量值 频数条形图:一个输入变量,需要注意连续x轴和离散x轴的差异。 直方图 与条形图不同的地方在于,x为连续型变量 ...
