[FEATURE] data as arrays

[benmccann]

I got a request in the financial repo to support data as arrays. See chartjs/chartjs-chart-financial#7

Right now the syntax below is supported (docs)

data: [{
        x: 10,
        y: 20
    }, {
        x: 15,
        y: 10
    }]

The request would like the following syntax to be supported as well:

data: [
    [10, 20],
    [15, 10]
]

[ortonomy]

data: [{ x: 10, y: 20 }, { x: 15, y: 10 }]
This syntax doesn't actually work.

@ortonomy it doesn't? cause it's documented here, https://www.chartjs.org/docs/latest/charts/bar.html#data-structure
