450: Forecast Maps / Bar Charts

A set of maps (or graphs if the Y-data are index format ) can be drawn to illustrate the forecasts for all grids / stations / series for a given forecast time. The forecasts can be displayed either as actual forecast values (or anomalies, or % departures, etc, based on the standardisation setting) with prediction intervals, or as probabilities or odds.

The map titles can be changed by right-clicking on the image and then selecting the Customise ~ Title option. The image can be exported as a graphics file. 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 ).

There is some flexibility to adjust the colour scaling: the colour bar limits can be set by right-clicking on the image and then selecting the Customise ~ Contour Limits option, and/or the number of colours can be set by selecting the Customise ~ Number of Colours option. In the case of index data, the graph Y-axis limits can be set using the Customise ~ Axis Limits option, and the number of tick marks can be set using the Customise ~ Number of Tick Marks option. Further options for customising the graphics, including adjusting the size of the fonts, and the size of the images, plus masking of land or lake areas for the maps are available from Options ~ Graphics .

The forecasts can be saved from the Forecasts tab from File ~ Output Results .
