Detailed Description

[library ilvcharts ilviews/charts/scaledis.h] Declaration of the classes involved in the scales display.


Define Documentation

#define IlvDefaultScaleArrowLength

This constant defines the default length for the arrow at the end of the scale axis.
The value of this constant is 8.

#define IlvDefaultScaleArrowWidth

This constant defines the default width for the arrow at the end of the scale axis.
The value of this constant is 8.

#define IlvDefaultScaleMajorTickSize

This constant defines the default size of the tick marks drawn for each step of a scale. We call steps the main graduations of a scale.
The value of this constant is 4.

#define IlvDefaultScaleMinorTickSize

This constant defines the default size of the tick marks drawn for each substep of a scale. We call substeps the secondary graduations of a scale.
The value of this constant is 2.

#define IlvDefaultScaleOffset

This constant defines the default offset between a graduation (or tick) and its associated label for a scale.
The value of this constant is 4.

#define IlvDefaultStepLabelFormat

This constant defines the default format for the numerical step labels of a scale. We call steps the main graduations of a scale.
The value of this constant is "%g".


Typedef Documentation

Defines the type of the callback function used to convert data values into step labels within an IlvAbstractScaleDisplayer object.

Given the data value associated with a step of a scale, the callback function returns the actual label that will be displayed for this step. The returned label must be a valid (not 0) C string allocated with the new operator.
