Syntax
grAddData(<Chart name> , <Series number> [, <Index>] , <Value>)
<Chart name>: Control name or character string Name of the chart to be used. This name corresponds to:- the chart name defined through programming with grCreate. This name must be in quotation marks.
- the name of the Chart control (in the window, page or report editor). This name must not be in quotation marks.
<Series number>: Integer Number of the series into which a value will be added.
For example, if the Chart control displays 2 lines, this is used to identify the line for which the data must be added. If the specified number does not exist, the series between the last existing series and the specified number are automatically created and initialized to 0. <Index>: Optional integer Index of the data in the series into which a value must be added.
For example, for a Line chart, this parameter corresponds to the X-axis of the value to add. If this parameter: - is not specified, the value is added at the end of the series.
- is specified, the former value is replaced.
<Value>: Integer or real Value to add. For example, for a Line chart, this parameter corresponds to the Y-axis of the value to add. Remarks Adding data - The data added by grAddData will be taken into account during the next call to grDraw.
- For a pie chart (grPie constant), only the data found in the first series is used. A Pie chart cannot be drawn if the data found in the first series is null.
- For the "Stacked bar" charts, if the value of the first series is negative, the corresponding bar is oriented toward the bottom.
Adding data into the different types of charts - For Scatter charts, it is recommended to use grScatterAddDataXY.
- For stock charts, it is recommended to use grStockAddData.
