Profits Graph

The profits graph shows how an investment of $1 apportioned according to the forecast probabilities would have resulted in a profit or loss for each forecast over the retroactive period or at each double cross-validated step. Profits and losses are averaged across all locations, but are not carried forwards to the next forecast.

The results can be saved by right-clicking on the graphs; the output file contains the results for all the weather roulette options ( Profits , Cumulative profits and Effective interest rates ). The graph itself can be saved as a graphics file by right-clicking anywhere in the child window and selecting Export from the pop-up menu. A default name is given to the graphics file, but this name can be changed using the browse button. The image quality for all the graphics formats can be improved by increasing the size of the image (see Options ~ Graphics ~ Graph Scaling ).

The y-axis limits can be set by right-clicking on the image and then selecting the Customise ~ Y-Axis Limits option. The maximum and minimum values on the y-axis are indicated and can be reset. Resetting these axis limits will in turn automatically reset the tick-mark interval and number of tick marks. Greater flexibility for setting the tick marks is planned for future releases. Further options for customising the graph, including adjusting the size of the fonts, and the size of the images, are available from Options ~ Graphics .
