Syntax 1 For data points in graphs

Description

Gets the value of a data point in a series in a graph.

Controls

Graph controls in windows and user objects, and in DataWindow
controls

Syntax

<span>controlname</span>.<span>GetData</span> ( { <span>graphcontrol</span>, } <span>seriesnumber</span>, <span>datapoint</span> <br>  {, <span>datatype</span> } )

1	<span>controlname</span>.<span>GetData</span> ( { <span>graphcontrol</span>, } <span>seriesnumber</span>, <span>datapoint</span> <br> {, <span>datatype</span> } )

Argument	Description
controlname	The name of the graph from which you want data, or the name of the DataWindow control containing the graph.
graphcontrol (DataWindow control only)	(Optional) A string whose value is the name of the graph from which you want the data when controlname is a DataWindow.
seriesnumber	The number identifying the series from which you want data.
datapoint	The number of the data point for which you want the value.
datatype (scatter graph only)	(Optional) A value of the grDataType enumerated datatype specifying whether you want the x or y value of the data point in a scatter graph. Values are: xValue! – The x value of the data point yValue! – (Default) The y value of the data point

Return Values

Double. Returns the value of the data
in datapoint if it succeeds and 0 if an error occurs.
If any argument’s value is null, GetData returns null.

Usage

You can use GetData only for graphs whose
values axis is numeric. For graphs with other types of values axes,
use the GetDataValue function instead.

Examples

These statements obtain the data value of data point
3 in the series named Costs in the graph gr_computers in
the DataWindow control dw_equipment:

integer SeriesNbr

1	integer SeriesNbr

double data_value

1	double data_value

// Get the number of the series.

1	// Get the number of the series.

SeriesNbr = &amp;

1	SeriesNbr = &

    dw_equipment.FindSeries("gr_computers", "Costs")

1	dw_equipment.FindSeries("gr_computers", "Costs")

data_value = dw_equipment.<span>GetData</span>( &amp;

1	data_value = dw_equipment.<span>GetData</span>( &

    "gr_computers" <span>,</span> SeriesNbr, 3)

1	"gr_computers" <span>,</span> SeriesNbr, 3)

These statements obtain the data value of the data
point under the mouse pointer in the graph gr_prod_data and
store it in data_value:

integer SeriesNbr, ItemNbr

1	integer SeriesNbr, ItemNbr

double data_value

1	double data_value

grObjectType MouseHit

1	grObjectType MouseHit

MouseHit = &amp;

1	MouseHit = &

    gr_prod_data.ObjectAtPointer(SeriesNbr, ItemNbr)

1	gr_prod_data.ObjectAtPointer(SeriesNbr, ItemNbr)

IF MouseHit = TypeSeries! THEN

1	IF MouseHit = TypeSeries! THEN

    data_value = &amp;

1	data_value = &

      gr_prod_data.<span>GetData</span>(SeriesNbr, ItemNbr)

1	gr_prod_data.<span>GetData</span>(SeriesNbr, ItemNbr)

END IF

END IF

These statements obtain the x value of the data point
in the scatter graph gr_sales_yr and
store it in data_value:

integer SeriesNbr, ItemNbr

1	integer SeriesNbr, ItemNbr

double data_value

1	double data_value

gr_product_data.ObjectAtPointer(SeriesNbr, ItemNbr)

1	gr_product_data.ObjectAtPointer(SeriesNbr, ItemNbr)

data_value = &amp;

1	data_value = &

    gr_sales_yr.<span>GetData</span>(SeriesNbr, ItemNbr, xValue!)

1	gr_sales_yr.<span>GetData</span>(SeriesNbr, ItemNbr, xValue!)
