ContEx v0.3.0 Contex.TimeScale 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.
