When in a voyage drawer the analysis tab is available in the tab section. In this tab you will be presented with a graph to give you a visual view of the development of key values in the selected voyage.

The graph that is displayed represents the total days for the columns, and the TCE for the line. These values can be changed in the dropdown fields on the top left. The timeline shown will be from the preliminary snapshot is taken to the current date. If the voyage is closed, the last value will be the last time the voyage was changed instead of todays date.
