1、julia怎么绘制直方图，纵轴为密度，然后拟合密度曲线  
2、julia怎么绘制正态分布曲线？  
3.或者julia对于r里的ggplot的…density…会无法识别要怎么修改？以下是我的r代码  
ggplot(data, aes\_string(x=“V5”)) +  
geom\_histogram(aes(y=…density…), # 这一步很重要,使用density代替y轴  
binwidth=1,  
colour=“black”, fill=“white”)  
4、julia怎么用ggplot画正态分布曲线

Google Translate says

> 1. How to draw a histogram in julia, the vertical axis is density, and then fit the density curve
> 2. How does julia draw a normal distribution curve?
> 3. Or how to modify julia for ggplot in r…density…will not recognize how to modify it? Below is my r code  
> ggplot(data, aes\_string(x=“V5”)) +  
> geom\_histogram(aes(y=…density…), # This step is very important, use density instead of y axis  
> binwidth=1,  
> colour=“black”, fill=“white”)
> 4. How to use ggplot to draw a normal distribution curve in julia
