Warning
From version 28 (75), Chart.Graduate is kept for backward compatibility. This function has been replaced with <Chart>.Interval.
Indicates the interval between values on the vertical and horizontal axis of a chart.
Reminder: By default, the interval is set to 0. This interval is adjusted to fit the available space in the selected destination.
Linux Caution: A specific configuration is required to use this function in Linux. For more details, see The charts.
Example
// Chart control
// Horizontal axis of chart with an interval set to 10
CHART_MyChart.Interval(10, grXCoordinate)
Syntax

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 <Chart>.Origin.
  • The data defined by <Chart>.Interval will be taken into account during the next call to <Chart>.Draw.
