CPT Help Home -> Specific Menu Items -> Tools -> Modes -> Y Loadings and Scores Y Loadings and ScoresIf gridded or station data are used, a map of the spatial loadings for each mode is shown, together with the temporal scores. If the data are unreferenced, a bar chart of the loadings is shown instead. The loadings are shown in the form of correlations between the original gridded/station/index data and the temporal scores. The results can be saved to an output file from the Modes tab in File ~ Output Results, but the actual loadings are saved rather than the correlations shown in the map. The graphics for each mode can be cycled by using the arrows at the top left of the graphics window, or by typing in the requisite number. Depending on your computer speed, you may need to wait a short time for the new graphics to display.The graphics can be saved as individually or as a montage as BMP, EMF, GIF, JPEG, PCX or PNG files by right-clicking anywhere in the child window, and then selecting the desired graphic to be saved from Export. A default name is given to the file, but this name can be changed using the browse button. The quality of the JPEG file can be adjusted using the slider or by the quality indicator, which ranges between 0.01 and 1.00. The highest quality is obtained using 1.00. The size of the JPEG file is affected by the quality chosen, with larger files being generated the higher the selected quality. The image quality for all the graphics formats can be improved by increasing the size of the image (see Options ~ Graphics ~ Graph Scaling). The map and graph titles can be set using the Customise option upon right-clicking in the child window. There is some flexibility to adjust the colour scaling on the map: the colour bar limits can be set by right-clicking on the image and then selecting the Customise ~ Contour Limits option. A window opens that indicates the assumed maximum and minimum data values when setting the colour intervals and number of colours. These values can be reset, which will in turn automatically reset the colour interval and number of colours. Similarly, the y-axis limits on the graph can be set by right-clicking on the image and then selecting the Customise ~ Y-Axis Limits option. Resetting these axis limits will in turn automatically reset the tick-mark interval and number of tick marks. Greater flexibility for setting the colour scaling and tick marks is planned for future releases. Further options for customizing the maps and graphs are available from Options ~ Graphics.
