Plot

A Plot node defines which plots are generated from the simulation results and where they are saved. Plots are only produced when at least one Plot node is defined (and plotting is not suppressed with the -s flag).

Example:

Plot "plots" {
    Directory = "./plots/"

    add_plot("global_emission_absolute")
    add_plot("global_fuel_consumed")
    add_plot("port_bunker_price")
}

Attributes

Directory

This attribute defines the directory in which the plots are stored, relative to the .nav file. The folder is created automatically if it does not already exist.

• Data type: String

• Format: Must be a valid directory readable by the Python ‘os’ module.

• Default: A plots folder next to the .nav file

Commands

add_plot

This command selects a single plot to be produced, by its label. Call it once per plot. If no add_plot command is given, every available plot is produced.

The label must be given as a quoted string, e.g. add_plot("global_fuel_consumed").

• Label: All available plot labels are listed in the Plot Labels section.

Appendix - Plot Node Labels

The labels below are the values accepted by the add_plot command on a Plot node. Each label must be passed as a quoted string, e.g. add_plot("global_fuel_consumed").
