I can only say that Sage isn't properly geared to plot non-smooth
functions.
If you have such a piecewise-linear graph, it's probably better to split it
into polyhedral pieces and plot them.

Recently I was trying to get SageMath to plot something:
plot3d(floor(min(x,y)),(x,1,7),(y,1,7))
The result looks like this:
I checked, and it does seem that both floor(min(7,1)) and
floor(min(1,7)) are equal to 1, as they should be. But that's not what
the plot shows. Any explanations of wha
