在ggplot2中,expand参数可以用于x轴和y轴的坐标轴设置。它是一个长度为2的向量,第一个元素控制坐标轴的左侧空白,第二个元素控制坐标轴的右侧空白。默认情况下,expand参数的值为c(0.05, 0),即左侧空白为坐标轴宽度的5% ,右侧空白为0。 expand参数的主要作用是调整坐标轴的扩展范围,以便更好地展示数据。当我们希...

在命令后面加上scale_y_continuous(expand = c(0,0))就可以了.长得也还好

对scale函数中的expand参数,需要是一个长度为2或4的向量。当长度为2,例如expand=c(0.1,0.2),表示分别向上下扩展10%,向上下加0.2,等价于expand=c(0.1,0.2,0.1,0.2),等价于expand=expansion(mult=c(0.1,0.1),add=c(0.2,0.2)),即expansion(mult=0.1,add=0.2)。
