Chart/graph that reconfigures with dropdown menu

The excel data set that I am trying to manipulate contains a long list of companies, dates, and profits. What I need to be able to accomplish is creating a drop down menu with the list of companies (that will be dynamically changed as companies are added or subtracted) and a chart that dynamically plots profit for each of the companies over the dates that have been given.

attached is a pdf sample of my list:
