Pre-Post Line Graph

[Ankit Bhardwaj]

Dear Statistician,
I want to create a before-and-after line graph for my dataset. Is it feasible in STATA? If yes, please help me with the command. I have attached an example.
No matches for the below command:
help twoway pcapsym

This can be seen as a follow-up to https://www.statalist.org/forums/for...tegories/page2

A glance at that will show that Ankit has already been asked for a data example and been given the suggestion to check
out twoway pcapsym.

Sorry; you need

help twoway pccapsym

but jusr rummaging around in the help would have solved that.

Thank you, sir. However, the line diagram created from the dataset "sysuse nlswide1" includes four variables. What do ttl_e68 and ttl_e88 represent in this "nlswide" dataset? I only have two variables for my data set, pre and post, and this command "twoway pccapsym" needs 4 variables.

Once again, I can't begin to guess exactly what you need without a data example. This kind of graph often needs the creation of an extra variable for the x axis if it doesn't exist.

Several examples in that spirit can be found in https://journals.sagepub.com/doi/pdf...867X0900900408
