Contex.TimeScale (ContEx v0.4.0) View Source

A time scale to map date and time data to a plotting coordinate system.

Almost identical Contex.ContinuousLinearScale in terms of concepts and usage, except it applies to DateTime and NaiveDateTime domain data types.

TimeScale handles the complexities of calculating nice tick intervals etc for almost any time range between a few seconds and a few years.

domain(scale, data)

Specs

domain(t(), [datetimes()]) :: t()

Define the data domain for the scale from a list of data.

Extents will be calculated by the scale.

domain(scale, min, max)

Specs

domain(t(), datetimes(), datetimes()) :: t()

Define the data domain for the scale

interval_count(scale, interval_count)

Specs

interval_count(t(), integer()) :: t()

Specifies the number of intervals the scale should display.

Default is 10.

new()
