Changes include:

• Extend Highcharts SeriesOptions interface with optional status property
• Update ChartSeriesMarker to accept and render status prop
• Pass status through chart legend and tooltip components
• Add visual examples in marker-permutations page for warning state

How has this been tested?

• Updated the permutations page.

• Updated the core line chart.

• Added unit tests.

Actually found this change is not accessible. Will work on updating that

Updated the warning icon to make it overlap a little with the marker:

you can create us a feature request to add support for this prop in the built-in i18n

The doubling of the marker sizes affected the spacing of the legend and tooltip items by a lot. I don't think we should do this: we can try to make the size increase smaller, and can also update the spacings of the legend and the tooltip.

Note that the PR has some conflicts to be solved.

Two suggestions here:

1. Rename to getItemOptions to be inline with Highcharts conventions and interface name
2. Update arguments to { itemId: string } type to allow for more options here in the future (name, etc.)

[pan-kot]

Also, please add ChartItemOptions to the CoreChartProps namespace (see how it is done for other props)

[Pixselve]

In that scenario, I would have loved to use a pattern I use a lot in Rust:

enum ItemIdentifier {
    Series(String)
    Point(String)
}

struct GetItemOptionsProps {
    item_identifier: ItemIdentifier
}

// then, you could do
fn getItemProps(props: GetItemOptionsProps) -> ChartItemOptions {
    match props.item_identifier {
        Series(id) => println!("props for series with id {}", id),
        Point(id) => println!("props for point with id {}", id),
    }
}

Anyway, covered your suggestions in the next rev. Thanks!
