How to plot a normal curve on a histogram

Back in 2017, txnelson posted a nice snippet of code to do this:

To scale the curve properly, you need the total number of data points divided by the data points for the maximum bar in the histogram distribution (here shown as 40/12 and 40/2) . Is there a way to calculate these? I can get the former, but not the latter.

 

Thanks for any help,

John

Re: How to plot a normal curve on a histogram

I do not know how to get the counts but assuming that the scale is appropriate, you could ask the Axis Box for the Maximum scale value with the << Get Max message.
