| Data Series | You can select whether to include historical data, trend of historical data, and forecast for future time in the trend view calculations. |
| Ranges for metric coloring | You can associate colors to metrics by entering a percentage, range, or specific state. For example, you can enter Powered Off in the Red Bound field when you select virtual machine as an object. You can set the colors only for views and not for csv or pdf formats. |
| Series Roll up | The time interval at which the data is rolled up. You can select one of the available options. For example, if you select Sum as a Transformation and 5 minutes as the roll-up interval, then the system selects 5-minute interval values and adds them.
