Javascript functions for populating creating Highcharts in div 2 of the dashboard.html webpage.

We will need to require the following two javascripts from Highcharts:
<script src="/http://code.highcharts.com/modules/exporting.js"></script>
<script src="/http://code.highcharts.com/highcharts.js"></script>

Note that this code has not yet been tested due to the need for database access.
