I am using Stata 15.1
I would like to create a secondary graph that focuses in on the output of a joint correspondence analysis. The sample code below uses the dataset as per the Stata manual info for MCA. When this graph is created i would ideally like to be able to place a rectangle around the points x = -2,2 y = -2,2 and then produce another graph that focuses on that area. Can someone please help me with code to do this?
