CPT Help Home -> Specific Menu Items -> Tools -> Verification -> Tendency Diagram Tendency DiagramThe tendency diagram shows the observed relative frequency of each category averaged over time and over all locations, and compares these with the average forecast probabilities for each of the categories.The statistics can be saved by right-clicking on the graphs; doing so saves the results of the Attributes Diagrams, which contains the tendency statistics. In a similar manner the tendency diagram itself can be saved and the title customised. The graph can be saved as a BMP, EMF, GIF, JPEG, PCX, or PNG file by right-clicking anywhere in the child window. A default name is given to the graphic 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 graphic title can be set using the Customise option upon right-clicking in the child window. Further options for customizing the graph, including adjusting the size of the fonts, and the size of the images are available from Options ~ Graphics.
