Stock price display
Now that we have a data frame nested by stock symbol, let's make a Trelliscope display with a plot for each stock. In this exercise, we use just the first 10 stocks in the by_symbol dataset we created in the previous exercise and create an "open-high-low-close" plot, a plot similar to candlestick plots. The available by_symbol dataset available in your session has already been subsetted to the first 10 stocks.
