The data selected for visualization is called a dataset. TotalView treats stack variables at different recursion levels or call paths as different datasets.

TotalView can visualize one- and two-dimensional arrays of integer or floating-point data. If an array has more than two dimensions, you can visualize part of it using an array slice that creates a subarray with fewer dimensions. Figure 150 shows a three-dimensional variable sliced so that one of the dimensions is invariant.
