You did provide enough info see that it was a length problem. But note
that there have been reports that plots failed because the data was
constant, so it's always hard to tell what the problem is without an
example.
Thus, a small example showing the problem is always useful.
BTW, I also sometimes plot 100,000+ points even though I know the screen
can't possibly actually show them all. I'm just looking for an interesting
section to plot in more detail, but I don't know where that is, and it's
just easier to ask for all the points instead of plotting every 5th or 10th
or 100th point.
