TdxChartXYSeriesLineMarkers.Size Property

Specifies size of value markers, in pixels.

#Declaration

Delphi
property Size: Single read; write;

#Property Value

Type Description
Single

The current size (in pixels) of value markers at 96 DPI. The property value can be 1 or higher.

#Remarks

Use the Size property to adjust size of value markers in a Line or Area series.

#Property Value Examples

Value Example[1]
8 (default) VCL Chart Control: A Simple Line Series with the Default Value Markers
4 VCL Chart Control: A Simple Line Series with Reduced Value Markers

#Property Setter Behavior

The Size property setter changes the property value to 1 if you assign a value below 1 to the Size property.

#Property Values and Scaling

The Size property specifies the base diameter (in pixels) of value markers that corresponds to 96 DPI. The Chart control’s draw routines multiply the Size property value by the current scale factor and round the result to the nearest integer to calculate the actual size of value markers on the target screen.

#Default Value

The Size property’s default value is DefaultMarkerSize.

Footnotes
