Hi,
I am facing the problem that I want to plot a histogram chart set
freq to true and overlay with normal or weibull or exponential distribution
curve.
The sample code is shown as below:
>samp<-c(-8.2262,-8.2262,-8.2262,-8.20209,-8.09294,-8.07321,-8.07321,
-8.07321,-8.07175,-8.04948,-8.04948,-8.04948,-8.03848,-8.03848,
-8.026,-7.92517,-7.92517,-7.77218,-7.62414,-7.62414,-7.62414,
-7.59027,-7.59027,-7.59027,-7.59027,-7.59027,-7.59027,-7.28924,
-7.28924,-6.78729,-6.25307)
>hist(samp,freq=TRUE,br=20)
>curve(dnorm(x,mean=mean(samp),sd=sd(samp)),add=TRUE)
In the chart created based on above command, curve scale is too small
compared to the freqeunce. My question here is how to adjust the scale of
distribution curve. Thanks !
Best Regards
WeiQiang Li
