title: How to graph change in market share over time in certain locations
body: <p>I'm thinking market share on y-axis, time on x-axis, and need to show my 5 different locations at each time. I have the data, just can't get a ggplot command to show me the locations all up on the same graph.</p>

  <p>So now I have 8 data frames like this one. The market share is in Nokia phones. How do I graph the changing market share per in each region over time?</p>
