Time Period Tabs
Charts can be viewed across different time ranges using the tab buttons at the top of the page:

Notes

The Charts feature must be enabled in the product's Client Area Permissions by the administrator.
The VM must be running to generate new data points. Historical data is available even when the VM is stopped.
Data granularity varies by time period: shorter periods show more detailed data points, while longer periods are averaged.
