Test legend ordering with explicate `series` parameter
Series order and legend order should match each other

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.
