Historic chart is accessible from the List View toolbar and Node context menus. The Historic Chart provides the same functionality as the charts displayed in Chart View but can be displayed directly from the Workspaces Tree, Map or List View without navigating away from your current view.
If you have assigned quality codes to the data, the associated quality code and color is displayed on hover.
Refer to working with charts for full details on chart interaction and functionality.
Filter the dataset by selecting quality codes associated with the data points that you want to include. While editing data, apply filters to automatically select associated data points and temporarily hide filtered data points to prevent modification.
Use this feature to toggle into data editing mode and display the data editing toolbar.
