Because arrays frequently have large amounts of data, TotalView provides a variety of ways to simplify their display.
The Variable Window in the upper left corner of Figure 6 shows a basic slice operation. Slicing tells TotalView to display array elements whose positions are named within the slice. (See “Displaying Array Slices”). In this case, TotalView is displaying elements 6 through 10 in each of the array’s two dimensions.
The other Variable Window in this figure combines a filter with a slice. A filter tells TotalView to display data if it meets some criteria that you specify. (See “Filtering Array Data Overview”). Here, the filter says “of the array elements that could be displayed, display only elements with a value greater than 300.”

While slicing and filtering reduce the amount of data that TotalView displays, you can also see the shape of the data. The Tools > Visualize command shows a graphic representation of the information in the Variable Window.
