TChartAxis.ExactDateTime
TChartAxis
property ExactDateTime: Boolean;
Unit
TeEngine
Description
Default Value: False
The ExactDateTime property controls if TChartAxis.TChartAxis.Increment property calculates Axis TChartAxis.Labels in exact DateTime steps.
This is very useful when TChartAxis.Increment is a DateTimeStep constant value:
Chart1.BottomAxis.Increment := DateTimeStep[ dtOneMonth ] ;
In this example, the Increment property should be considered to be an exact month. So, if an axis label is:
'1-April-2007'
then the next axis label would be:
'1-May-2007'
and the next:
'1-June-2007'
When ExactDateTime is False (the default value), the dtOneMonth increment equals to 30 days, and axis do not calculate how many days a month has.
The Series TChartSeries.XValues or TChartSeries.YValues properties should have the TChartValueList.DateTime property True. ( XValues for horizontal Axis and YValues for vertical Axis).
