Plot coefficients over time

[Mateus Maciel]

I know that many people asked this question but I still struggling to solve my issue.

I am running the following regression:

xtreg log_var did tratamento agencia log_volume_cobrado log_pib_percapita log_densidade, fe vce(cluster id_municipio)

"did" is my differences in differences estimator, which came from the interaction of "tratamento" and "agencia". I want to plot the values of this coefficient over time, and my time variable is "ano."

Hola. It seems like you're asking for the heterogeneous treatment effect of your intervention at time T0, T1.... TN, right?

Yes, Jared! I would be glad if you could help.
