Class Detail
links.Graph.StepDate(start, end, minimumStep)
Parameters:
{Date} start
The start date, for example new Date(2010, 9, 21) or new Date(2010, 9, 21, 23, 45, 00)
{Date} end
The end date
{Number} minimumStep
Optional. Minimum step size in milliseconds
Method Detail
{string} addZeros(value, len)
Add leading zeros to the given value to match the desired length. For example addZeros(123, 5) returns "00123"
Parameters:
{int} value
A value
{int} len
Desired final length
Returns:
{string} value with leading zeros

{boolean} end()
Check if the end date is reached
Returns:
{boolean} true if the current date has passed the end date

{Date} getCurrent()
Get the current datetime
Returns:
{Date} current The current date

getLabelMajor(date)
Returns formatted text for the major axislabel, depending on the current date and the scale. For example when scale is MINUTE, the major scale is hours, and the hour will be formatted as "hh".
Parameters:
{Date} date Optional
custom date. if not provided, current date is taken

getLabelMinor(date)
Returns formatted text for the minor axislabel, depending on the current date and the scale. For example when scale is MINUTE, the current time is formatted as "hh:mm".
Parameters:
{Date} date Optional
custom date. if not provided, current date is taken

{boolean} isMajor()
Check if the current step is a major step (for example when the step is DAY, a major step is each first day of the MONTH)
Returns:
{boolean} true if current date is major, else false.

next()
Do the next step

roundToMinor()
Round the current date to the first minor date value This must be executed once when the current date is set to start Date

setAutoScale(enable)
Enable or disable autoscaling
Parameters:
{boolean} enable
If true, autoascaling is set true

setMinimumStep(minimumStep)
Automatically determine the scale that bests fits the provided minimum step
Parameters:
{Number} minimumStep
The minimum step size in milliseconds

setRange(start, end, minimumStep)
Set a new range If minimumStep is provided, the step size is chosen as close as possible to the minimumStep but larger than minimumStep. If minimumStep is not provided, the scale is set to 1 DAY. The minimumStep should correspond with the onscreen size of about 6 characters
Parameters:
{Date} start
The start date and time.
{Date} end
The end date and time.
{int} minimumStep
Optional. Minimum step size in milliseconds

setScale(newScale, newStep)
Set a custom scale. Autoscaling will be disabled. For example setScale(SCALE.MINUTES, 5) will result in minor steps of 5 minutes, and major steps of an hour.
Parameters:
{links.Graph.StepDate.SCALE} newScale
A scale. Choose from SCALE.MILLISECOND, SCALE.SECOND, SCALE.MINUTE, SCALE.HOUR, SCALE.WEEKDAY, SCALE.DAY, SCALE.MONTH, SCALE.YEAR.
{Number} newStep
A step size, by default 1. Choose for example 1, 2, 5, or 10.

snap(date)
Snap a date to a rounded value. The snap intervals are dependent on the current scale and step.
Parameters:
{Date} date
the date to be snapped

start()
Set the step iterator to the start date.
