Adding a top margin or padding to Top of subplot drawing area

is there a way to add a top padding to a subplot. as can be seen below, i have some info i want to display in the upper left of each subplots (highlighted in yellow). but depending on the data i am plotting, it may get overwrriten/hidden. if could add a TOP padding area to the sublot, that would solve the problem i think. I have tried using the a spec = [[{‘t’:.5]],[{‘t’:.5]],[{‘t’:.5]]] when calling make_subplot, but that does not do anything it seems.
