st: CDF log-normal and histogram

[Beatrice Crozza <beatrice.crozza@gmail.com>]

Dear All,

I want to have a graph which combine the histogram of frequencies for
my variable and on the same graph an empirical CDF of data and a
fitted CDF (log-normal)

I can do the histogram in this way:
histogram var1, freq

To see if my variable follows a log-normal I do:
dpplot var1, dist(log-normal)

The CDF of my variable in this way:
distplot var1,

How can I combine the histogram with the empirical CDF and the fitted
CDF (log-normal)?

I tried with twoway but it doesn't work.

Thank you very much for your help.

Best,
Bea
