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
>>
