seems like stroke should be a separate configurable no?

A chart with grid but without stroke looks kind of weird. So I guess we would always want to add stroke when there is grid being enabled. And when there is no grid being enabled, we can let the user setup the option to disable stroke? What do you think?

With stroke.

actually I think stroke might be something we'd always want to keep unless overriden

@jeanservaas could you please chime in?

There is the situation when we don't want to show the stroke.

why do we need this extra classname?

The reason why we need chart-grid-backdrop-no-stroke classname is because we don't want to apply stroke around the chart when there is no grid line.
