Type alias: TickMarkFormatter()

TickMarkFormatter: (time, tickMarkType, locale) => string | null

The TickMarkFormatter is used to customize tick mark labels on the time scale.

This function should return time as a string formatted according to tickMarkType type (year, month, etc) and locale.

Note that the returned string should be the shortest possible value and should have no more than 8 characters. Otherwise, the tick marks will overlap each other.

If the formatter function returns null then the default tick mark formatter will be used as a fallback.

Example

const customFormatter = (time, tickMarkType, locale) => {
    // your code here
};

Parameters

• time: Time

• tickMarkType: TickMarkType

• locale: string

Returns

string | null
