TdxChartCrosshairLabelAppearance.ImageSize Property

Specifies pixel dimensions of crosshair label item glyphs.

#Declaration

Delphi
property ImageSize: TdxSizeFloat read; write;

#Property Value

Type Description
TdxSizeFloat

ImageSize.Width and ImageSize.Height property values specify width and height (in pixels) of the area allocated to a crosshair label item glyph at 96 DPI.

#Remarks

Use ImageSize.Width and ImageSize.Height properties to shrink or expand areas allocated to item glyphs within the crosshair label pane layout.

#Property Value Examples

ImageSize.Width Value ImageSize.Height Value Example[1]
20 16[2] VCL Chart Control: The Default Glyph Dimensions in the Main Crosshair Label
10 8[3] VCL Chart Control: Shrunk Glyphs in the Main Crosshair Label
30 24[4] VCL Chart Control: Increased Glyphs in the Main Crosshair Label

#Property Values and Scaling

ImageSize.Width and ImageSize.Height properties specify the base pixel dimensions of a crosshair label item glyph area that correspond to 96 DPI. The Chart control’s draw routines multiply ImageSize.Width and ImageSize.Height property values by the current scale factor and round the results to the nearest integer to calculate the actual item glyph dimensions on the target screen.

#Default Value

Default ImageSize.Width and ImageSize.Height property values are 20 and 16, respectively.

Footnotes

  2. The default glyph dimensions.

  3. Smaller series glyphs reduce the main crosshair label size.

  4. Larger series glyphs expand the main crosshair label size.
