How to overlay empirical cumulative distribution over histogram?

[Markos Valsamis]

I am able to get a histogram as well as the empirical cumulative distribution as two separate graphs using the below commands:

hist continuous_variable, freq

and

cumul continous_variable, gen(ecdf) equal

However, I have not been able to figure out a way to overlay them on the same plot. I would be grateful for your advice.

An example of my intended output graph (example sourced from google photos) is appended here:

Some technique:

sysuse auto, clear 

set scheme s1color 

sort mpg 

cumul mpg, gen(cdf)

twoway histogram mpg, width(1) yaxis(1) || line cdf mpg, c(J) yaxis(2)
