TdxRangeControlDateTimeScale.IncDate(Double,Int64) Method

Retuns the viewport coordinate of the next date/time value tickmark corresponding to the beginning of the next whole time interval equal to the measurement unit used to graduate the scale.

Declaration

function IncDate(const AValue: Double; AIncrementValue: Int64 = 1): Double; virtual;

Parameters

Name	Type
AValue	Double
AIncrementValue	Int64

Returns

Type
Double

Remarks

Normally, this function supports the internal infrastructure and is not intended to be used directly from your code. The IncDate function is called internally by the range control to determine viewport tickmark positions on the scale.

The AValue parameter specifies the viewport coordinate of the original date/time value.

The AIncrementValue parameter specifies the number of measurement units by which AValue should be incremented.

If you are implementing a custom date/time scale, you may need to override the IncDate function in a TdxRangeControlDateTimeScale descendant in order to graduate the scale in custom measurement units.
