The View menu supports either
Graph or
Surface visualization. When TotalView sends a new dataset to the Visualizer, the Visualizer updates its dataset list. To delete a dataset from the list, click on it, display the File menu, and then select Delete. (It’s usually easier to just close the Visualizer.)
This item is a toggle; when enabled, the Visualizer automatically visualizes new datasets as they are read. Typically, this option is left on. If, however, you have large datasets and want to configure how the Visualizer displays the graph, disable this option.
