Indicates the step for the marks on the vertical/horizontal axis of a chart (which means the interval between two marks).
Reminder: The step for the marks is set to 0 by default. This step is adjusted to best fit the available space in the selected destination.
Example
// Chart created by programming
// Vertical axis of the chart with a step set to 5
grGraduate("MyChart", 5, grYCoordinate)
// Chart control
// Horizontal axis of chart with a step set to 10
grGraduate(CHART_MyChart, 10, grXCoordinate)
Syntax
grGraduate(<Chart name> , <Step> [, <Type of axis>])
<Chart name>: Character string (with or without quotes)
Name of chart to use. This name corresponds to:
  • the chart name defined by programming with grCreate.
  • the name of Chart control found in the window editor, page editor or report editor.
<Step>: Real
Interval between two marks. If this parameter is equal to 0, the step will be adjusted to best fit the available space in the selected destination.
<Type of axis>: Optional constant
Type of the axis for which the step is defined:
grXCoordinate
(Default value)		Marks on the X axis.
Versions 18 and later
grZCoordinate
New in version 18
grZCoordinate
grZCoordinate		Marks on the Z axis (Surface chart only).
grYCoordinateMarks on the y axis.
grSecondaryYCoordinateMarks on the secondary X axis.
Remarks

Marks on axes

  • Limits: 100 marks above and 100 marks below the "X" axis.
  • The last mark displayed is the first multiple of <Step> greater than the highest data value. The entire data is displayed regardless of the destination dimension.
  • To modify the start and end marks on the horizontal, vertical or secondary axis of a chart, use grOrigin.
  • The data defined by grGraduate will be taken into account during the next call to grDraw.

Types of charts

The marks on axes have no effect on the Pie charts.
