An example of a graph view is shown in the image below.
When viewing results the Analysis Toolkit is used. If you want to view more than one plugin at once or would like to view a graph or threshold view then you can use the buttons shown below.
Modify will allow you to add/remove plugins from the results and the View buttons allow you to change between table, graph and thresold.
These options are explained in the Analysis Tookit section of the manual.
