// Vertical axis of the chart with an interval set to 5
grInterval("MyChart", 5, grYCoordinate) // Chart control
// Horizontal axis of chart with an interval set to 10
grInterval(CHART_MyChart, 10, grXCoordinate) Syntax
grInterval(<Chart name> , <Interval> [, <Type of axis>])
<Chart name>: Control name or character string Name of the chart to be used. This name corresponds to:- the chart name defined through programming with grCreate.
- the name of the Chart control in the window, page or report editor.
<Interval>: Real Interval between two marks. If this parameter is set to 0, the interval will be adjusted to fit the available space in the selected destination. <Type of axis>: Optional constant Type of the axis for which the interval is defined: | | | grSecondaryYCoordinate | Marks on the secondary X-axis. | grXCoordinate
(Default value) | Marks on the X-axis. | | grYCoordinate | Marks on the Y-axis. | | grZCoordinate | Marks on the Z-axis (Surface chart only). |
Remarks Marks on axes - Limitations: 100 marks above and 100 marks below the X-axis.
- The last mark displayed is the first multiple of <Interval> 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 grInterval 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.
