Lower limit defines the maximum acceptable value for the bottom
of the graph.  It can get lower.    The upper limit is a minimum,
the value can get higher.

So: "--lower-limit 0 --upper-limit 100" will show *at least* from
0 to 100.  It can also be -10 to 110.

Not graphing the data outside the perimeters is done using the
rigid option.  That same "--lower-limit 0 --upper-limit 100" will
only show 0 to 100, no more no less.

cheers,
