What kind of visualizations do you use?

opened 03:57PM - 24 Jun 20 UTC
Fixes https://github.com/elastic/kibana/issues/68403
This PR exposes the `ela… stic-charts` fitting functions (except for "Explicit") as a chart-level setting of the xy-chart.

The popover for now only contains a select for the fitting function, other options like color palette will be part of the same popover in a later iteration

If there is no line or area series, the select will be disabled (state will still be carried along)

For Pie charts there is no popover menu in the toolbar (if it gets added later because of other features, it won't contain the select at all)
## Architecture
On an expression level, there is a new optional string argument `fittingFunction` on the `lens_xy_chart`, taking all available options. If no value is provided, it defaults to `None`, maintaining the old behavior - this means no migration is necessary, saved Lens visualizations will simply run an expression without a `fittingFunction` argument.
