Test axis domain min/max values values + clamping

It is possible to extend axis scales. And it is possible to shrink axis scale by manually providing scale domain min/max values, however without having "clamp":true it will not crop data plotting itself, but only affect axis positioning on graph, while adding "clamp":true actually applies data plotting cropping.

type=year

xAxisMin=1994 | xAxisMax=2020 | yAxisMax=120 | yAxisMin=20 | yZero=false
