直方图的大小，在R图中具有正态分布

Question

我使用以下代码生成具有所属正态分布的直方图

如何减小绘图的大小，以便能够在绘图中看到整个正态分布？

Answer 1

const ref = firebase.database().ref('bookmarks')
    .orderByChild('date')
    .startAt(date.end)
    .endAt(date.start)
    .limitToLast(10)

边距和图表大小

  

您可以使用以下参数控制边距大小。

df   <- data.frame(rnorm(1000), rnorm(1000))
h    <- hist(df[,1], breaks=10, density=10, col="lightgray", xlab="Accuracy", main="Overall")    
xfit <- seq(min(df[,1]),max(df[,1]),length=40) 
yfit <- dnorm(xfit,mean=mean(df[,1]),sd=sd(df[,1])) 
yfit <- yfit*diff(h$mids[1:2])*length(df[,1]) 
par()$pin
par(pin=c(2,2))
lines(xfit, yfit, col="black", lwd=2)
