Release 5.4.0

Minor changes to improve API docs and add extra configuration option added to Vega Lite 5.6.

V5.4 Additions

• fromPosixTime to allow Elm time functions to be used to generate elm-vegalite DateTime values. Thanks to @RalfNorthman for the suggestion.

• secoZero to set the default for whether zero is included in the domain of a scale (VL5.6).

Corrections

• Correct loGrouping bug that generated a single locale grouping rather than array. Thanks @hingew for spotting this.

API Documentation

• Corrected API doc for coLocale example to use correct Elm unicode escape text.

• Added reference to parent functions to some functions in the API docs. This makes it easier to see how a function is used in the context of a larger specification by navigating up the function dependency tree. Thanks to @RalfNorthman for the suggested improvement. Note: this is a work in progress and will be extended to other functions in future releases.

Deprecations

• Deprecated dtMonthNum as it was redundant (use dtMonth instead). There should be no reason to allow specification of months with numbers as this carries the risk of undefined behaviour for integers outside the range [1,12]. Thanks to @RalfNorthman for spotting this.

• AxisChoice, axX and axY deprecated as specific axis choice is specified via coAxisXFilter and coAxisYFilter. These have been redundant since elm-vegalite V2.3.0 but were inadvertently left exposed in the API.
