I have been having an issue graphing one of my variables in a time series database. My data set contains a variable called "Stock" which contains the names of different stocks for a period of time ranging from 2010-2018. I am able to graph each specific stock by using an "if" restriction, but I would like to have several series or stocks within the same graph. As the stocks alphabetical variables, Stata treats them as string and I cant just simply graph all of them.

How could I de-string stock names or merge different series into a single graph.

Thanks, and I look forward for any help I can get.
