| | `hoverBackgroundColor` | `Color[]` | The fill colour of the arcs when hovered. | ||
| | `hoverBorderColor` | `Color[]` | The stroke colour of the arcs when hovered. | ||
| | `hoverBorderWidth` | `Number[]` | The stroke width of the arcs when hovered. | ||
| | `legendSymbol` | `String[]` | Symbol to display as label when usePointStyle is false (size is based on fontSize except for large symbol (ending with Lg) where boxWidth is used in this case). Values are rectLg, lineLg, rectRoundedLg and other values from [PointStyle](./elements.md/#point-styles) |

I think it might make sense to split large vs small into a separate boolean.

or, if boxWidth is defined, use it else use the fontSize
…e (boxWidth) or not (fontSize as width)

New legendSymbolLarge property has been added. |

You might be able to use helpers.getValueOrDefault since this pattern is used in a few places.
| pointStyle: dataset.pointStyle, | ||
| legendSymbol: itemLegendSymbol, | ||
| boxWidth: (opts.usePointStyle && (fontSize * Math.SQRT2)) || (itemLegendSymbol.slice(-2) === 'Lg' ? opts.boxWidth : (fontSize * Math.SQRT2)), | ||
| legendSymbol: (opts.usePointStyle && (dataset.pointStyle || defaults.global.elements.point.pointStyle)) || dataset.legendSymbol || (opts.legendSymbol), |

does legendSymbol negate the need for the pointStyle property on the line above? If so, is removing it a breaking change?

I don't knw that fontSize should be a param here. height makes a lot more sense.
