如果您查看下面的图表(y轴),您会注意到刻度从0
到0.20
。我有其他直方图,范围是从0
到0.4
。我想使它们都一致从0
到1
并显示y
轴从0
到1
。
conne <- file("C:Aisdefined.bin","rb")
sd <- readBin(conne, numeric(), size=4, n=1440*720, signed=TRUE)
y <- t(matrix((data=sd), ncol=1440, nrow=720))
r <- raster(y)
f <- hist(y, breaks=10,main="sm")
f$counts <- f$counts/sum(f$counts)
dat <- data.frame(counts= f$counts,breaks = f$mids)
ggplot(dat, aes(x = breaks, y = counts, fill =counts)) +

在 y 轴值为 0 的下方包括空间,当没有数据点在 0 以下时? - SabreWolfy
