Graph Combine Issues

Hi everyone, first time posting here.

I have a series of graphs with post-operative day (time) on the x-axis and a percentage on the y-axis. I would love to merge all the graphs into one (each one is generated from rather lengthy .do files). Is there a way to have all the graphs overlayed with different color lines for each data set if they share the same x axis and same y range?



As far as I know you need to create such a graph with one command. If your do-files are all working from the same dataset this should be relatively straightforward; otherwise you may need to create a "summary" dataset from each do-file, combine then, and then produce the graph.
