Use scale defined in the chart when x/y ScaleID options are not set

[stockiNail]

TODO

• documentation update

If we will start going to V2 and due to element normalization, maybe it could be helpful to define the sequence of PR merging in order to help the rebasing, where needed. My 2 cents.

I think that would be your task, because you've done all the work. So maybe just keep things as draft and mark the next one ready after merge.

Fine for me. In fact, they are all in Draft, apart of the V2 migration page one which must be the first one.
