Truman had 250, Ike 181.... then they started going away... 44 for GHWBush (in 4 years), 37 for Clinton (8 years... averaging 4.6/yr), 12 for GWBush (8 years... 1.5/yr), 12 for Obama (8 years... 1.5/yr), and now 1 in 2 years (0.5/yr) for Trump the Tyrant (according to the MSM).
You have to go back to the 1800s for Garfield to find a president with zero.
(You have to go back to 1825-1829, John Quincy Adams, to find a full term President with zero vetoes.)
Did the decrease in Presidential vetoes correspond to a decrease in Congressional bills submitted for signature? or it is a case where Congress does more talking than doing, and the executive branch takes more actions without specific congressional law making about it?
