Plotting odds ratio vs. continuous variable in stata

Is there any way I can plot a graph like this in stata:

linear OR of age;

The odds ratio is from a logistic regression.

I want to plotting the odds ratio of every value of the continuous variable and set reference as the lowest value. "margins" seems meet my need, however, I have to list all values of the continuous variable so that it can calculate the OR. Another question is I want plot this graph on another graph plotted by "twoway", and I'm not sure how to do this in stata.

You basically answer your own question, it's an issue of using margins with marginsplot. The details are described in this post, but you would do something like:

logit outcome age, or
margins, at(age=(38(1)82)) expression(exp(xb()))
marginsplot

For your second question take a look at the marginsplot documentation. Similarly to other stata graphs it can be combined with other plots.
