TdxRangeControlCustomDateTimeHeaderClientProperties.GetMinSelectedInterval Method

Returns the minimal selectable range for a Date/Time Header-based data range selection and visualization model.

Declaration

function GetMinSelectedInterval: Variant; override;

Returns

Type
Variant

Remarks

Normally, this function supports the internal infrastructure and is not intended to be used directly from your code. The GetMinSelectedInterval function is called internally by the range control to identify the real minimal selectable range (in measurement units of the currently active predefined scale) when a date/time range is selected.

The GetMinSelectedInterval function returns 1, indicating that none of the Date/Time Header-based data range models allow you to select an empty range or the range corresponding to a fraction of the current measurement unit. As a result, the range control always has the date/time range selection corresponding to at least a single whole measurement unit of the active scale.
