Hello Matthew Nelson,
It is really easy to switch between types of charts. If you want to display your local working example as a line, all you need is to set
chart.type property in your code to 'line'. API:

Try to analyze your code, check your console and compare your code with a code from working example. If you couldn't find what is wrong share your code and we will try to help
