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 #
How to display a time
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 |
| -> 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.
Utilities
doubleFromLocalTime :: LocalTime -> Double Source #
Map a LocalTime value to a plot coordinate.
