Name	Value	Description
exStartDate	0	Indicates that the starting date or time of the scrolling range is accessed or requested.
exEndDate	1	Indicates that the ending date or time of the scrolling range is accessed or requested.
exMinDate	2	This option is read-only, so setting the exMinDate has no effect. Instead use the exStartDate. Retrieves the minimum date when the chart's scrolling range is specified by Chart.ScrollRange(exStartDate) and Chart.ScrollRange(exEndDate). For instance, you can specify the .Items.ItemBar(Item, "newbar", exBarMinStart) = .Chart.ScrollRange(exMinDate) to limit the starting point of the bar to the scrolling range.
exMaxDate	3	This option is read-only, so setting the exMaxDate has no effect. Instead use the exEndDate. Retrieves the maximum date when the chart's scrolling range is specified by Chart.ScrollRange(exStartDate) and Chart.ScrollRange(exEndDate). For instance, you can specify the .Items.ItemBar(Item, "newbar", exBarMaxEnd) = .Chart.ScrollRange(exMaxDate) to limit the ending point of the bar to the scrolling range.
