- Marks on axes
- Types of charts
- Restoring the default values
<Chart>.Origin (Function) In french: <Graphe>.Origine Modifies the start and end marks on one of the chart axes. Note The function <Chart>.Origin function allows you to view only part of the graph, by reducing the values displayed on one of the axes.
gnYMin is int
gnYmax is int
gnYMin = GRF_Graphe..YAxisMin
gnYmax = GRF_Graphe..YAxisMax
GRF_Graphe.Origine(500, 1000, grYCoordinate)
GRF_Graphe.Dessine()
GRF_Graphe.Origine(gnYMin, gnYmax, grYCoordinate)
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 (in the window, page or report editor).
<Minimum mark>: Real Start mark on the specified axis.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.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:
| | | grSecondaryYCoordinate | Secondary Y-axis (vertical axis). | grXCoordinate
(default value) | X-axis (horizontal axis). | | grYCoordinate | Y-axis (vertical axis). | | grZCoordinate | Z-axis (Surface charts only). |
Remarks Marks on axes - X-axis (horizontal axis): the parameters <Graduation minimale> and <Graduation maximale> correspond to the minimum and maximum index of data in the series displayed.
- Y-axis (vertical axis): the parameters <Graduation minimale> and <Graduation maximale> correspond to the minimum and maximum value of the data.
- Limits: 100 graduations above and 100 graduations below the x-axis.
- To modify the frequency of marks on the horizontal or vertical axis of a chart, use <Chart>.Interval.
- 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:
| | | XAxisMax | The XAxisMax property gets the maximum value of the X-axis in a Chart control. This property can be used in the "Zoom" event of a Chart control to identify the section displayed. | | XAxisMin | The XAxisMin property gets the minimum value of the X-axis in a Chart control. This property can be used in the "Zoom" event of a Chart control to identify the section displayed. | | YAxisMax | The YAxisMax property gets the maximum value of the Y-axis in a Chart control. This property can be used in the "Zoom" event of a Chart control to identify the section displayed. | | YAxisMin | The YAxisMin property gets the minimum value of the Y-axis in a Chart control. | | ZAxisMax | The ZAxisMax property gets the maximum value of the Z-axis in a Chart control (Surface chart). | | ZAxisMin | The ZAxisMin property gets the minimum value of the Z-axis in a Chart control (Surface chart). |
