If you look at the graph below (y axis), you will notice that the scale is from 0 to 0.20. I have other histograms where the range is from 0 to 0.4. I want to make all of them consistent from 0 to 1 and display the y axis from 0 to 1.
如果查看下图（y轴），您会注意到刻度为0到0.20。我有其他直方图，范围从0到0.4。我想让它们从0到1保持一致，并显示从0到1的y轴。
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)) +
geom_bar(stat = "identity",alpha = 0.8) +
xlab("Pearson correlation")+ ylab("Frequency") +
scale_x_continuous(breaks = seq(-1,1,0.250), labels = seq(-1,1,0.250)) +
ggtitle("2011") + theme(axis.title.x = element_text(size = 20)) +
theme(axis.title.y = element_text(size = 20)) +
theme(text = element_text(size=20),
axis.text.x = element_text(angle = 90, vjust=1,colour="black"),
axis.text.y = element_text(colour="black")) +
theme(plot.title = element_text(size = rel(2.5))) +
scale_fill_gradientn(colours = "black")

Just add:
只需添加：
+ coord_cartesian(ylim=c(0,1))

Try this:
尝试这个：
scale_y_continuous( limits = c(0,1), expand = c(0,0) )
