Modifies the start and end marks on one of the chart axes.

Remark: The <Chart>.Origin function allows only part of the graph to be viewed, reducing the values displayed on one of the axes.

Example

// Modification de la graduation de début et de fin sur l'axe vertical du champ Graphe "GRF_Graphe"
// La graduation ira de 500 à 1000
// Restauration des valeurs par défaut

// Initialisation de fenêtre
gnYMin est un entier
gnYmax est un entier

// Bouton de modification de la graduation
gnYMin = GRF_Graphe..AxeYMin
gnYmax = GRF_Graphe..AxeYMax
GRF_Graphe.Origine(500, 1000, grOrdonnée)
GRF_Graphe.Dessine()

// Bouton de restauration de la graduation
GRF_Graphe.Origine(gnYMin, gnYmax, grOrdonnée)
GRF_Graphe.Dessine()

Syntax

<Chart name>.grOrigin_object(<Minimum mark> [, <Maximum mark> [, <Type of axis>]])

<Chart name>: Control name

Name of the Chart control to use (found in the window editor, page editor or report editor).
Only the interactive Chart controls are available.

<Minimum mark>: Real

Start mark on the specified axis.
Versions 23 and later
This parameter can also correspond to a duration, a date, a time or a date-time.
New in version 23
This parameter can also correspond to a duration, a date, a time or a date-time.
This parameter can also correspond to a duration, a date, a time or a date-time.

<Maximum mark>: Optional real

End mark on the specified axis. If this parameter is not specified, <Maximum mark> corresponds to the maximum value of chart data.
Versions 23 and later
This parameter can also correspond to a duration, a date, a time or a date-time.
New in version 23
This parameter can also correspond to a duration, a date, a time or a date-time.
This parameter can also correspond to a duration, a date, a time or a date-time.

<Type of axis>: Optional constant

Axis for which the marks must be modified:
grXCoordinate
(default value) X axis (horizontal axis).
Versions 18 and later
grZCoordinate
New in version 18
grZCoordinate
grZCoordinate Z axis (Surface charts only).
This constant is not available.
grYCoordinate Y axis (vertical axis).
grSecondaryYCoordinate Secondary Y axis (vertical axis).

Remarks

Marks on axes

X axis (horizontal axis): <Maximum mark> and <Minimum mark> correspond to the maximum and minimum data values in the series displayed.
Y axis (vertical axis): <Minimum mark> and <Maximum mark> correspond to the minimum and maximum data values.
Limits: 100 marks above and 100 marks below the X axis.
To modify the frequency of marks on the horizontal or vertical axis of a chart, use <Chart>.Graduate.
The data defined by <Chart>.Origin 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.

Restoring the default values

To restore the display of the chart before the origin was modified, the minimum and maximum values of axes must be saved. These values can be known via the following properties:


Versions 14 and later XAxisMax New in version 14 XAxisMax XAxisMax	The Property AxisXMax allows to know the maximum limit of the abscissas (X axis) of an control of type Graph. This property can be used in the zoom process of a chart to identify the section displayed.
Versions 14 and later XAxisMin New in version 14 XAxisMin XAxisMin	The Property AxisXMin allows to know the minimal bound of the abscissas (X axis) of an control of type Graph. This property can be used in the zoom process of a chart to identify the section displayed.
Versions 14 and later YAxisMax New in version 14 YAxisMax YAxisMax	The YAxisMax property is used to determine the upper bound of the Y-axis in a Chart control. This property can be used in the zoom process of a chart to identify the section displayed.
Versions 14 and later YAxisMin New in version 14 YAxisMin YAxisMin	The YAxisMin property is used to determine the lower bound of the Y-axis in a Chart control.
Versions 18 and later ZAxisMax New in version 18 ZAxisMax ZAxisMax	The Property AxisZMax allows to know the maximum limit of the altitudes (Z axis) of an control of type Graph (Surface graph).
Versions 18 and later ZAxisMin New in version 18 ZAxisMin ZAxisMin	The Property AxisZMin allows to know the minimum bound of the altitudes (Z axis) of an control of type Graph (Surface graph).

Versions 20 and later

Remark: <Chart>.Zoom can also be used to view a section of the chart. However, the final user can restore the initial configuration via the popup menu of the chart ("Initial zoom").

New in version 20

Remark: <Chart>.Zoom can also be used to view a section of the chart. However, the final user can restore the initial configuration via the popup menu of the chart ("Initial zoom").
