Well, I was wrong and I apologize. The problem only occurred with data columns of very large values, but it wasn't caused because those values exceeded a 32-bit integer. Instead, the problem was the "set ytics" command.
I had been using "set ytics 1 ..." to try to force only integer values. Seeing non-integer tics which the data is only integers in misleading and confounds viewers. What I was doing works great when the values are small but seems to go into a very long loop when the values are very large. I will now make my process a bit more elaborate and compute a proper tic interval.
Unless there is some other, more direct, way to specify that automatic tic marks should only be integers?
