Synopsis

Documentation

type TimeSeq = LocalTime -> ([LocalTime], [LocalTime]) Source

TimeSeq is a (potentially infinite) set of times. When passed a reference time, the function returns a a pair of lists. The first contains all times in the set less than the reference time in decreasing order. The second contains all times in the set greater than or equal to the reference time, in increasing order.

type TimeLabelFn = LocalTime -> String Source

timeAxis Source

Arguments

:: TimeSeq	Set the minor ticks, and the final range will be aligned to its elements.
-> TimeSeq	Set the labels and grid.
-> TimeLabelFn
-> TimeLabelAlignment
-> TimeSeq	Set the second line of labels.
-> TimeLabelFn	Format `LocalTime` for labels.
-> TimeLabelAlignment
-> AxisFn LocalTime

Create an AxisFn to for a time axis.

The values to be plotted against this axis can be created with doubleFromLocalTime.

autoTimeAxis :: AxisFn LocalTime Source

Automatically choose a suitable time axis, based upon the time range of data. The values to be plotted against this axis can be created with doubleFromLocalTime.

days :: TimeSeq Source

A TimeSeq for calendar days.

months :: TimeSeq Source

A TimeSeq for calendar months.

years :: TimeSeq Source

A TimeSeq for calendar years.

Utilities

doubleFromLocalTime :: LocalTime -> Double Source

Map a LocalTime value to a plot coordinate.
