Chart

A mixed chart of the calculation results is generated at the bottom. Each port call has multiple graphs to show the reductions, cargo quantity and quantity available for cargo. The charts gets updated automatically when there are changes to the voyage header, port call, or vessel parameters.

Click on the legends at the top of the chart to toggle the display of a graph. Hover the mouse over the chart to inspect the values of each calculation data point.

Loadline Information

The loadline information table shows data on the voyage vessel that might affect the intake. To change these values, you need to edit the vessel in the Vessels module in master data.
