<Chart>.Interval (Function)

In french: <Graphe>.Graduation

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 graduation pitch is 0. This interval is adjusted to fit the available space in the selected destination.

Caution: In Linux, this function requires a specific configuration. For more details, see The charts.

Example

// Champ Graphe
// Axe horizontal du graphe gradué avec un pas de 10
GRF_MonGraphe.Graduation(10, grXCoordinate)

Syntax

<Chart control>.Mark(<Step> [, <Type of axis>])

<Chart control>: Control name

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.

<Step>: 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).
This constant is not available.

Remarks

Marks on axes

Limits: 100 graduations above and 100 graduations 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.

Types of charts

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