To insert, change or delete individual data items from the event history, use the Event History table. Click the Event History link on the Data Editing table to open the event history for a specific tag. By default, the Event History table displays data for the same range as the Data Editing table, but you can change the date settings in the Event History screen.

**To insert, modify or delete individual data history values:**

1. Enter a new date range if necessary and click **Reload data** to load the filtered data in the Event History table.
2. Enter a new default time if necessary or accept the existing default. A set of empty fields for the default time will automatically be added to the table for each day (unless there is already an existing event at that time).
3. You can now change, delete or insert any values within the date range:
  - To change a data value or time stamp, select the event and enter a new value and click **Update**. Note that you can modify existing values as well as enter new values in unpopulated fields.
  - To insert a new event at a time other than the default, enter the event details in the New Event table and click **Insert**.
  - To delete an event, select the Delete check box and click **Update**.
