Title: add forceOrdinateOrigin option

Hello,

I've been in the situation where a value in my graph was extremely different from others :

In that case, we decided it was ok not to see the extreme value (with a "start at 0" toggler, actually) rather than having such a flat graph.

To do so, I added a options.grid.y.forceOrdinateValue, which prevent minValue to be changed (given that the user provided a startAt value too).

The result is this :

I'm not sure you will want such a behaviour, but it's here if you want it.
