TdxCustomRangeControl.VisibleRangeMaxScaleFactor Property

Specifies the maximum ratio between the available and visible data ranges.

#Declaration

Delphi
property VisibleRangeMaxScaleFactor: Double read; write;

#Property Value

Type
Double

#Remarks

The range control’s “scale” (or “zoom”) factor is a ratio between the entire data range available for selection and the data range portion currently visible within the control’s viewport. The smaller the difference between the VisibleRangeMinValue and VisibleRangeMaxValue property values, the grater the range control’s “zoom factor”.

{Image}

Use the VisibleRangeMaxScaleFactor property to set the upper limit for the range control’s “zoom factor”, which can be set by:

Note that while the range control’s “zoom factor” cannot be less than 1 (i.e., the selectable range must occupy the entire range control’s viewport area), the currently active data range selection and visualization model determines which VisibleRangeMaxScaleFactor property values are acceptable.
