Without knowing anything about this structure array, my in-the-dark advice is to try converting the struct array to a cell array or table.

The screenshot of the Command Window shows that the data-20.mat contains Qt, which is a <1x22000 struct>.

I assume that Qt has a field called val, the value of which you want to plot. Try plot([a.Qt.val])

Example

a.Qt(1).val = 1;
a.Qt(2).val = 2;
a.Qt(3).val = 3

outputs

a = 
  struct with fields:
    Qt: [1×3 struct]

and

>> [a.Qt.val]
ans =
     1     2     3
