The `parallel_coord2` function creates a parallel coordinates plot of a set of provided configurations. Each line in the plot represents a configuration.
The parameters to be included in the plot can be selected with the param_names argument. Additionally, the maximum number of parameters to be displayed in one plot. A list of plots is returned by this function in several plots are required to display the selected data.
To export the plot to a file, it is possible to do it so manually using the functionality provided by plotly in the plot. If a file_name is provided, orca server will be used to export the plots and thus, it requires the library to be installed (https://github.com/plotly/orca).
parallel_coord2( configurations, parameters, param_names = parameters$names, by_n_param = NULL, file_name = NULL )
| configurations | Data frame, configurations in irace format (example: configurations = iraceResults$allConfigurations) |
|---|---|
| parameters | List, parameter object in irace format (example: configurations = iraceResults$parameters) |
| param_names | String vector, names of the parameters that should be included in the plot (example: param_names = c("algorithm","alpha","rho","q0","rasrank")) |
| by_n_param | Numeric (optional), maximum number of parameters to be displayed |
| file_name | String, file name to save plot (example: "~/patch/example/file_name.png"). Orca is required. See more details in: https://github.com/plotly/orca |
